The guy that takes the joke one step too far

[private joker]

Think of this as a cousin to the "jokes that flopped IRL" thread.

Does everyone know that guy who wants to get in on the joke of the room but always takes it a step too far, just going over the line to the point where it simply becomes awkward for everybody? I was reminded of this today when the following scenario came up.

Guy walking into office slips on the door handle and ends up ramming himself right into the door before opening it, so his torso was pressed against the closed door. He walks in and laughs it off, saying "wow sorry I think I just humped that door in front of you guys."

Person A: hey, it turned me on. (Everyone chuckles).
Person B (guy taking it a step too far): Yeah, haha. I think I have a hard-on!

Then everyone just kind of puts their head down hoping the moment goes away.

Share your examples of the guy that took the joke one step too far.
