"Derpy is as Derpy does"
"Life is like a box of muffins"
I've got hundreds of these I could go on....
This picture took way longer than I originally intended, mostly because I'm crap at shadows. But I feel this came out okay, I just thought Derpy and Forrest are quite interchangeable, though I am not saying Derpy has mental problems, I'll leave that up to the fanfic writers to decide
As a sidenote: all the little text at the bottom has been lifted straight from the original Forrest Gump poster. In the interests of time.
Hope you like it, comments are appreciated
