Some people consider dick jokes to be the lowest common denominator of humor.  Others consider them to be the staple of good comedy.  You will find both of the a fore mentioned types of people in this video... 

Needless to say, the girl getting the shadow dick shoved in her ear is the type of person who doesn't enjoy a good dick joke.  However, the guy with the shadow dick seems to fall in the "good comedy" camp of dick jokes.

After watching that video, I need to know... WHAT THE HELL IS THE SHADOW DICK!?  Did this kid bring a dildo to class or what?
