me 3, me 4

Last few days while we were out for dinner, in the car my sons were watching the "Iron Man" show. Conversation as below....

Cruz: i like the red colour iron man

Fearles: me too (two)!!

Cruz: me THREE !

Fearles: me FOUR!

mummy: o..O *speechless*

Actually i did overheard this before, "me too, me three, me four and sometime me five!" I don't know what they talking about, till that night in the car. I told them there is only "me too" "too" only..no three or four or five!!!! They argue with me somemore! *slap forehead*
