Well, there's too many of them but I'm gonna try my best to pick one
for each!

Ted: When he stands by the window to greet the Chinese, whilst
unfortunately next to that rectangular piece of dirt.

Dougal: After jumping off the milk float, when he takes off his
milkman gear and jumps into the air yelling, "I'M A PRIEST!"

Jack: In Competition Time, when he's dressed as Elvis, then looks at
Ted and says (in a placid manner), "Who are you supposed to be?"

Mrs Doyle: It's gotta be the first time she falls off the window in
the xmas episode.

Maybe some odd choices there, but the best bits I could think of at
the mo. Obviously got loads more but just to get the ball rolling.
What about everyone elses fave character moments?!
Jess.
