The Janitor Quotes

# Dr. Cox: I am getting rid of Maddox. Who's in?
Janitor: I'm in. Ever since she fired me I've been moping around my apartment making barking sounds. I'm not crazy, I just need some human interaction and the barking makes the neighbors yell 'shut that damn thing up'. Then I can go over there with a bottle of scotch and apologize for Rusty, my imaginary echida. The only downside is that by the time Lady, my girlfriend, gets home, I'm too drunk to talk to her, much less make love. You've never pictured me as an organism that has sex, have you?
Dr. Cox: We have not, no.

Dr. Cox: How are we going to get rid of Maddox? Janitor, would you like to get your useless ideas out of the way first?
Janitor: Well thank you Perry. Off the top of my head I'd go reindeer stampede, astronaut attack, barbed wire chandelier, photoshop, poisonous sushi
