We duct taped a FNG to the toilet in Flight Ops and took his flight suit and laid it on the ramp with a "remove before flight" streamer on it. He helped us torment the next FNG. That's what makes RONs more interesting.
The 'remove before flight' streamer was a nice touch!
I've heard it is routine to do a little 'repainting' when an aircraft from another carrier makes an unscheduled visit.
