Underwear

One single word, spoken outloud, can send Kayli into gales of laughter, as seen in the picture below!

I might say "Kayli, what should we have for dinner?" she replies "How 'bout macaronicheese aaaand (appears to be thinking hard) aaaand UNDERWEAR! AHaHaHaHa, AHaHaHa, Yuck Yuck Yuck, then, Hey Mom, how 'bout some strawberries ummm, wearing UNDERWEAR! AAAAhahahah!"
Nope,there's nothing like 4-year-old humor!
