Ahhhh, I was watching it with the speakers turned off, so when it said 'dad' and 'kid', I figured they were meaning his kid, not someone elses, so yeah, hopefully he'll find some new buddies when it comes to shower time...
On the other hand, I'm also a big believer in the philosophy that if some punk thinks they're man enough to mouth off to someone, they have to be man enough to deal with the consequences, and I'll bet the kid's learned a lesson he won't forget in a hurry... As you say, pure White Trash... Gotta love it
