When my son was young he used to love Buzz Lightyear and he often repeated Buzz's favourite saying "I'm Buzz Lightyear, I come in peace". Except when junior said it, it came out as "I'm buzzed like you, I come in pissed". lol It made me laugh every time.
My son has come out with some corkers, a recent one, he announced that he'd like to go to Mercury, and that he'd build a special space suit so he doesn't get "lava ' d" then go to Pluto, to see if there's penguins there.
He's also said he'd like to own a Lama, so it can carry his stuff when he goes on holidays!
One of his first words for a fruitbar was "dubbar", he'd ask for "dubbars" all the time
My brother as a young child used to get confused with the words Raccoon and Fir cone, and used to call Helicopters "Cop-doctors"
I popped my head into my son's room last night to check he'd fallen asleep. He sat up, looked at me and said he really needed a toy ladder. I asked what he needed it for and he said he needed to climb up to the moon. He then lay down and fell back to sleep. I sometimes wonder what he dreams about.
