The thread about which way to face bird boys in the derby and the deviation you will deal with over the course of a series got me thinking back to some (funny now, but at the time - not so much) bird boy issues when judging.
More than once i've had a bird boy stand up and start walking out of the field after throwing a bird so he can use the restroom. We've had to send a four wheeler out to pick up a kid who demanded he be taken to the porta potties. Once had a bird boy walk out of the field in the open because his coach told him he could leave at 1pm and he was tired of dealing with us (remember that Kippy??).
Most recently we had a bird girl have an asthma attack in the field while a dog was running. That was pretty scary.
