I find it fun to put funny pics on forums just to make people smile every once in a while, let's face it everone needs to sometimes.
if you have funny photos or drawings/cartoons you want to post then please do. just make sure they are appropriate.
Someone once posted this picture on the forums and I found it hilarious:

Oh, I just got a message that my post was too short
(that was a first!)
just wanted to post:
FUN!

Lol! There's a first time for everything! 
Awesome pics, Pika! 
thank you for the laughs on this boring Thurs. morning in SC!
PS My favorites were 1) seriously, get off my lawn 2) the rules may be arbitrary, etc, but God help you if you break them (I hate rules!!!) and 3) the 'fro hairdo.
Oh and it's impossible not to laugh at Captain Kirk with that swarmy smile on his face. Impossible!

Love this kind of humor. Especially after years of nausea from workplace motivational posters. The "Demotivators" at Despair are not only funny, thy have nice photography.
