What did this lad do?

Bobby has been tormenting Custer the Goat for months.  He has been very clever, making sure no one's caught him doing it.  His abuse knows no limits.  He's kicked Custer, thrown garbage at him, tried to light his tail on fire, and insists on dressing him in women's clothes.  The little goat has finally had enough.  He's finally fighting back, making it clear this is Custer's Last Stand. 

I think the color of his shirt is the trigger.

yeah
he wore the wrong color 
t shirt for sure
and maybe he didn't give them their treats in the bag. This post was edited by Baba at October 9, 2017 11:55 PM MDT

Little Johnny hit on the goats wife.

nothing, the goat knocked him down

Little Johnny should have minded his own business instead of telling the goat that Randy was being unfaithful. Goats get pissed when their partners cheat on them.
