A couple months ago, my son got a GIR tee shirt. (GIR is from the cult cartoon Invader Zim, which we both adore) Anyhow, on the front, GIR is holding a Cupcake, and there is a thought balloon over his head with a picture of a cupcake and a symbol: cupcake <3 My son and I for months have been trying to figure out why a cupcake is less than 3. (yes, we are both math geeks) I JUST realized it is an emoticon heart. D'OH!!!!
