My six year old son started an entrepreneurship called Painted Pennies. He draws mustaches and hats on pennies, and sells them for $0.50. During his grand opening yesterday, he accepted donation purchases - the pennies were free, you just donated whatever you had to his piggy bank fund to help him get started with his business so he could expand to other coins. ♥ Oh, and he's open 24/7.
Just had to share. I love that kid. ;)
