How do you handle a partner like this?

[archangel]

Worked JV game last week, where my partner (who I didnt know, and was maybe about 65) was already dressed for the plate when I arrived 30 min prior. He stated that he hadnt worked the plate yet this year, and though I prefer the dish, I told him, it was OK with me.
I'm in A to start the game, just finished answering a Q from the base coach, and am watching F1 deliver the 1st pitch. Afterwards, I hear a fan behind the backstop yell to my partner "wheres your mask?". He had laid it down nearby and just forgot it.
Between one of the middle innings, I'm in right field when I see him walk into 3rd base dugout(team was taking the field), and with his back to all - is standing by the trashcan with his hands in front down low! I figured he had a weak bladder but I was still shocked! He zipped up, came out and started the inning. No one that might've seen said a word, and I went to right ea time till game end. As we left together, walking by the same dugout, he ducked in and grabbed his "cup", saying that he forgot to wear a jock, and the cup kept slipping down so he had removed it midgame(I was wrong on the weak bladder thought).
I just know that if I did either of these, I'd be hurting in 2 places for sure....Oh, and he did call a good game....
