I don't need or want some pseudo-analysts to tell me why Blue Collar Comedy would be funny to someone who relates to it. Same goes for sitcom humor, "look how bratty my child is" humor, "hurt defenseless beings" humor, or "I'm a total asshole" humor. I mean, duh. I know why those things are funny to those people - because they're idiots.
No, I'm kidding, I mean that I know that different things are funny to different people.
Do we really have to explain what a spoof is? Who wouldn't understand what a send-up is? Or irony, or sarcasm, over-the-top-ness?
Lordy Lou, you gotta be kidding me.
