I have one of myself-short n sweet:
Apparently when I was little, I would say pancakes made me angry. Dunno why, but it always pissed off my dad

.
Now for my 5 year old nephew:
His grandma: Hey *nephew* do you like me in this skirt
Nephew: Its looks weird, but a good kind of weird.
My roomie: What does a platypus say
Nephew: A platypus doesn't exist cause it is a bitch

(he only curse around us

)
Me: Say Percy (when Clash of the Titans came out I was explaining the story to my roomie. Yes I know the name is not Percy, thats all my nephew heard)
Nephew: *Says Percy in a way that sounds like another term for a lady part. Use your imagination*
Now we get him to say random phrases with the word Percy. We are so bad
