One of mine are the partners that won't even make eye contact with you. They would prefer to stare off into space, into the stands or right into the ground. Then they look at you funny when you call an infield fly because they weren't aware of the situation or the fact you were signaling it pre-pitch. :rolleyes:

Sometimes I feel like takin out a baseball and chucking it at them.

Or yelling during a dead period "Did he go?!" just to see their reaction.

Only hand signal I didn't see mentioned was the hand in the shape of holding a mug similar to hang loose sign. This is flashed at partner when he boots a call or misses a rotation. Meaning...you owe first round!
