I ended up on a committee mine was in once.
I had a less vocal role, though I was known as the kid who made all the idiotic jokes.
We stopped working with each other around then coincidentally, so it wasn't really a problem.
I was asked if it would be weird, but I replied that there's a completely different relationship outside that room; and I thought we were both professional enough to respect each other enough to work together. (I however, had a lot of weird feelings during the time- not enough to cause me to rescind though_)
It worked out well.
