I love quoting TV shows. I think it brings people together as they can share the in-joke. Some quotes I say are:
TTFN. tat ta for now - Tigger from Winnie the Pooh
Yabba Dabba Doo - Fred from The Flintstones
Indeed - Teal'c from Stargate SG-1
I have a cunning plan - Baldric from Black Adder
Stupid boy - Captain Mannering from Dad's Army
Don't panic! - Corporeal Jones from Dad's Army
What's Up, Doc? - Bugs Bunny from Looney Tunes
You're Despicable - Daffy Duck from Looney Tunes
Oops, what's oops? I don't like oops - The Doctor from Star Trek Voyager
