I love it when my kids try to say words they can't pronounce.
My youngest one loves tomatoes but has the hardest time saying it. It comes out binaydos, which she uses for the word potatoes too. Makes me laugh every time! My oldest one, when she was little, said truck and luck, and anything else that ends with an "uck" sound with *uck. I was embarrassed at first, but thinking about it now just makes me laugh. Too funny when she says the sound of a chicken...it goes *uck, *uck!
A sound I'm sure my hubby doesn't think is too funny, but I have to bite my lip every time he does it. My hubs is 6'7" and most doorways here are 6'8" doors. When he's wearing shoes and walks with a little bounce in his step, he scrapes the top of his head on the top of the door way. The sound though, that cracks me up is the string of swear words that follow. It really shows his creative side! LOL!
