Buzzer

I was just talking to the supervisor at the day program I work at (but who isn't my actual supervisor). We were having a somewhat awkward, extraneous but semi-important conversation as we walked down the hall. She finally got into the elevator, holding it to prolong our awkward, awkward conversation. Finally, the elevator alarm went off, "ENNNNNG," sounding much like a basketball buzzer. This forced us to make final closing statements and wrap up our conversation.

I think conversation buzzers would be great. I was going to keep going with this, and give some funny examples of conversations that should be cut off, but I think that's a Chappelle's Show sketch. So never mind!
