Stick your finger in my mouth and I will bite too.
I'll keep that in mind Bill. Does your dentist have any fingers missing?
The only story I know of a toothy fish causing trouble was when a C.O. tried to arrest two young Native Americans for a violation on the border of their reservation. They pinned him down, pulled is pants down and shoved a foot long walleye up his ***. Needless to say it had to be surgically removed! Now that had to hurt!
