4 year old genius

Yesterday Garty and I stopped at a supermarket that had a giant blow up piggy bank out front. When we picked the other kids up from school, Garty was telling them about it. He explained that we saw a huge piggy bank at the "butt money store." I couldn't figure out why he would say something like that until I realized that the store was called "Bottom Dollar Food." Evidently he's really good with synonyms.
