I typed in "Havin' fun" in a google image search. Here's some of the wonderous things I found:
The Havin Fun Quartet. (that's really their name)
The one in the dark pink shirt looks like she's the dirty one.
It actually looks like she's goosing the woman on the right.
Hmm.....I guess that could be fun.
More havin fun:
Right after this picture, the guy on the right slapped that guy in the nuts.
That dog was gone in two bites.
