This is one of the few episodes where Vicky isn't the one who babysits Timmy.
This episode reveals how Timmy got his buck teeth in the first place. It was because Pappy unintentionally let Timmy suck on his pacifier too long as he forgot momentarily where he was.
This episode was ranked #14 in the "100 Greatest Nicktoons Episode" countdown.
Pappy was born in the 1930s, so that means he's somewhere in his Eighties. Also, he has a vast amount of knowledge on old cartoons, since he tells Timmy about lots of things that normally happened in old cartoons.

Vicky could just turn the lever for the buzz saw on fast instead of slow.
