The Professor: Good luck! And Skunk-Ape? Thanks again for safely disposing of my little GARBAGE PROBLEM.
Skunk-Ape: Er... Yeah...'Safely...'

Howie: I'm guessing he means the radioactive material in your garbage pile that created our giant pumpkin?
Skunk-Ape: AND his giant kitten.

The Professor: And REMEMBER, Howie! One sip per day of the wolf serum, or it's dog food for dinner for the rest of your life!

(earth shakes and a very loud 'meow' is heard with giant footfalls indicating the imminent arrival of enormous and apparently hungry kitten)
The Professor: Why did I say 'dinner'?
