I've got quite a few of them here that I'll try to share with you:

I used to be a ramp controller for my airline at a busy hub. We controlled lots of transiting traffic to/fro the runway along with the gates at the concourse. A Delta 737-200 called me to cross the ramp, and I gave him clearance to cross. This guy was taxiing at an incredible rate of speed. It was a slow day, I key up my mic and say "V1....rotate". Delta crew came back on and said "yeah, sorry bout that. The captain just did a Mexico overnight and the food has reached the end of its trip"
