People with lisps can't say the word lisp. Who. What kind of person thought that was a good idea? Probably the same guy who supervised the Olive Garden commercials:
Waiter: And for you, sir?
Family Man: ...I'll have... The Usual!
*Intense family laughter*
Someone should have told that guy that if he wanted to appeal to the family demographic, he should have made the family seem like actual human beings. Sure, the whole "allusion to an inside joke because we're too lazy to actually come up with a good joke" might have worked in a remedial filming class, but this man is a professional, and even in that situation, there still needs to exist at least the barest pretense of wit.
