2-year-olds say funniest things

Sean's been pretty funny lately. At the dinner table today we were trying to teach him say "grandma". Sean pointed at me and said "Mommy" and then pointed at Mike and said "Daddy" and he proceeded to grandma and said "Baka". It's funny because 'Baka' in Japanese means moron. We laughed so hard until we had tears in our eyes. We say "no, Sean it's graaanma" but with a big grin he repeats "Baka". He thinks he is saying it correctly and pretty proud of it. Well, moron it is. My Mom does not seem to mind (as yet).
