You're Walking Down The Hallway

Young man, where did you get this toad?
It's not mine!
Chris, you don't wanna mess with drugs.
I tried 'em once,
Big mistake.
Thanks, Dr.
Peter, man.
You're walking down a hallway,
Take a left.
You keep walking down the hallway,
Take a right.
Then a left, then a right,
Then a left, then a right,
Then a left, then a right,
Then a brick wall.
You keep walking down a hallway,
Take a left.
