Its pretty self explanitory, its a guy in a jump suit with an orange wig who goes around kicking people in the nuts. It got canceled after these two shows but there is a DVD coming out.

What kind of dumbass father is happy to see his two children and self kicked in the balls by some random nutter with hair like that?

Uhh I'm pretty sure it's all staged.

Well that's what I thought, which moves me on to my second question:

What kind of dumbass father would allow his two children and self to be kicked in the balls by some random nutter with hair like that?

I don't think they actually got kicked if it were staged. Maybe they had cups or maybe the man stopped short of an actual kick.
