I love the Professor!! I try to use his responses as often as possible even if people have know idea what I'm talking about
Philip J. Fry: Fetal stem cells? Aren't those controversial?
Prof. Hubert J. Farnsworth: In your time, yes. But nowadays... shut up!
I sometimes try to work in Professor Farnsworth's exchange to Glurmo about the Grunkalunkas into conversation.
"What are those things?"
"Tell them that I hate them!"
Sadly it's kind of hard to find a context to use it.
Leela "They're the gentle giants of the sea"
Proffesor "I'm well aware of that!"
leela- do you know what might be a hoot?
Farnsworth- No, why would i know that.
