What is the most frustrating thing your partner(s) have done?

I am lead. Play in the middle of the key. I need popcorn, M&M's, and a large coke I have such a great view. Defender blocks shot, squeaky clean. Partner, from Trail, maybe 1/2 step inside the halfcourt line, calls a foul. Adds the editorial comment, for all to hear,

"C'mon partner, we gotta call that".

I believe he's still cleaning the puke off his shoes today. With his good arm.
