Peter Piper Pizza commercial just slays me

I don’t know why but the Peter Piper commercial running out here lately just slays me.

A short desription of the commercial. The announcer guy rattles off the special they are running. The special is something like a large pizza, 4 sodas and some game tokens for $20. Anyway it cuts to a shot of a family of three.

The dad:“Can I get a large pepperoni?”
Announcer guy:“Yes.”
Mom:“Can I get a diet Pepsi?”
Announcer guy:“Yes.”
Little girl:“Can I get a little sisthster?” The girl has a big lisp.
Dad:“Yes.”
Mom:“No.”
Dad:“Well we could…”
Mom:“NO!”

It then cuts back to announcer guy.

Every time I see this commercial I burst out laughing. The little sister line is just so perfect in a WTF? kinda way.

Does anyone else find this commercial to be high humor?
