"The Simpsons" I'm Spelling as Fast as I Can (TV Episode 2003) - Harry Shearer as Ribwich Ad Announcer, Principal Skinner, Lenny, Ribhead #1, Kent Brockman, Otto, Ribhead #2

Bart Simpson : Come on, man, everyone knows the first day of school is a total wank.

Principal Skinner : Well, if by "wank" you mean educational fun, then stand back it's wanking time!
Otto : Spell AC/DC!

Lisa : A-C-D-C

Otto : Nuh-uh! You forgot the lightning bolt.
Principal Skinner : [an announcement made in front of the entire school] Due to budget cuts we had to sell the plastic skeleton and replace it with this Halloween costume. Also, the class trip to Italy is now "Spaghetti Night" in the school cafeteria, and your $1500 deposit is non refundable. Goodnight!
