Butterflies Eat Poop (and other observations of a five year old)
I was gonna write a book full of witty things and such but faced a couple of major obstacles:
1. I'm not witty or even remotely funny
2. I don't know (or have) any five year olds
I'm pretty sure these things are what they refer to as "deal killers"... crap!
...and someone else has already beat me to the t-shirt idea.
