Worked with two guys and this was the joke they played on new guys. First guy acts like a hard ass towards second guy to make new guy think they’re not friends. 1st guy tells new guy that 2nd guy smells good. Keeps up the joke all day. Finally tells new guy “hey go ask 2nd guy what he’s got in that smells so good.”

Proceed with punchline of the joke.

Also works anytime a guy notices your cologne and you’re around the boys.
