Let's hear it. My just-turned-4 year old today: "Daddy, grandma said her grandma and grandpa died. Does that mean she's gonna die too?" He's got some doozies.
my nephew (real nephew, not the snoopdog "aw wassup nephew" kind) once heard me curse up a storm and went back home emulating me while hitting a stick on a wall, screaming "schitte schitte schitte schitte schitte schitte schitte schitte..." so now his dad won't let him come over to my place again.
