Doug first appeared in "The One With The Ultimate Fighting Champion" where he is quickly revealed to be a friendly, good-natured and boisterous, but at the same time shallow and ego-centric man who has an unusual symbolic method of congratulating his male employees for their good work-by slapping them on the backside. He doesn't seem to perceive this behaviour as being in any way inappropriate, and doesn't seem to be able to realize on his own that other men may not be comfortable with him doing this, which indicates that he personally has little, if any, intimacy issues with other men, but at the same time is so self-absorbed and close-minded that he lacks the ability to see things through the perspective of other people and is therefore incapable of realizing on his own that other men might have them. When he starts slapping Chandler on the buttocks, the other employees get jealous, taking the fact that he only ever slaps Chandler's jacksey as a sign that he isn't really noticing their good work, only Chandler's. Chandler himself isn't comfortable with this however and asks Doug not to do it to him anymore. Doug agrees when he realizes he is making Chandler feel uncomfortable, but when he begins slapping his other employee's buttocks in order to congratulate them for their good work, Chandler becomes jealous, feeling that they are receiving praise for good work that he no longer is. Overcome with jealousy, he talks to Doug and persuades him to start slapping his backside again.
Although he never appeared onscreen with them, it was mentioned that Doug, his wife Kara, and the rest of Chandler's co-workers met Joey at some point when he was invited to a work office party by Chandler. It is implied that Joey's stupidity greatly irritated and drove every single one of them crazy, as Chandler claimed, in the midst of telling Monica how much they all loved her after he first introduced her to them, that he believed she had "repaired a lot of the damage from when they met Joey."
Doug next appeared in "The One With Chandler's Work Laugh" where Chandler and Monica go to a work office party where they can enjoy being a couple. However, Monica doesn't like Chandler sucking up to his boss and his annoying "work laugh," which he reserves for Doug's bad jokes when he pretends to find them funny. Apparently, every single one of Chandler's co-workers suck up to Doug in this manner as well, which could possibly be the reason behind his inflated ego and self-absorbed attitude. Doug and Kara love Monica so much that they invite both her and Chandler to play tennis at their house where Chandler goes to great lengths to let Doug win because Monica is determined to win, exhausting, irritating and bemusing Doug and Kara with her ridiculously overly-competitive attitude. They are later invited to dinner where Monica persuades Chandler to drop the 'work laugh'. However, when Chandler neglects to laugh at Doug's bad joke about how weak Kara's coffee is and tells Doug he didn't find it funny, he inadvertently comes across as being rude and unfriendly, and when it becomes clear that Doug is starting to take offence, Monica is forced to, in a subtle manner, tell Chandler to resume his sucking up, and his work laugh.
It was mentioned that Doug was invited to Chandler and Monica's engagement party, but he got drunk and urinated on their ice sculpture, causing them to ban him from the wedding.
Doug's last appearance is in "The One With Ross' Step Forward" where it is revealed that he and Kara have divorced. He mentions that he had ended up in court a number of times charged with sexual harassment, but he kept "knocking (the lawsuits) out of the park." He invites Chandler and Monica to dinner, but Monica still hasn't forgiven him for the ice sculpture incident, so Chandler tells him that Monica and him have split up so that she won't have to come. Doug takes him to a series of bars and strip clubs to help him forget Monica. He has a horrible time as Doug gets more and more drunk. However, he later tells Monica that the worst thing of all about that night was seeing the depressed and emotionally fragile state Doug has now been reduced too as a result of losing Kara; because that to him was a glimpse of how he would end up if he ever lost Monica. He asks Monica to promise him that she will never leave him, and grow old with him. And she meanfully promises she will.
