spectacular spiderman!

i'd gotten caloway a spiderman lunch bag at target last night - they were 75% off! anyway, i pulled it out of the car for him tonight, and he was so excited, he kept saying, "mom! thanks for my pe-taccalar spiderman bag!" over and over ... i couldn't figure out what he was saying, so I asked him,

"what is it again?"
"Mom! Thanks for my petacular spiderman bag!"
Oh! Your "spectacular" spiderman bag?
"Yeah, my pectaccalar spiderman bag!"

Since when does he use the word Spectacular?! it was just so cute, i could eat him up! love that boy!
