Chimpanzees, rubber pants

Called home last night and really wish I could have seen the look on the wife's face.

B: Hi! How do you say "rubber pants" in Bulgarian?
long pauseK: What pants?
B: Rubber.
long pauseK: Where the hell are you?!?!
B: [Coworker]'s office
K: гумени панталони

It now says on my coworker's whiteboard that he is "Сексапилен като шимпанзе в гумени панталони." (Sexy as a chimpanzee in rubber pants)

I'm sure he's overjoyed.
