Oh, goodness.  Urine humor.

Tricky to do urine humor.  Lotta audience variability on the ol’ urine.

For all the ladies reading- those are “urinals” the the Ghostbusters are standing in front of.

You might wanna look up some old George Carlin routines about urinals, too.  George was an insightful person, and so, like Lin, was able to make use of urine and urinals for humorous purposes.

You can visit Lin, as always, at Have Geek Will Travel.
