Beakman's World Season 4 Episode 2

Beakman: I'm sad to report that earthworms are blind.
Lester: On the bright side, however, they don't have to look at other earthworms.

Lester: Oh, it's not enough I get humiliated week after week. Now, I'm expected to be a mind reader?

Beakman: You don't want to know how I did it?
Lester: Are there burritoes involved?

Beakman: I'm all keyed up for a question. Phoebe, unlock a letter for me.
Phoebe: Unlocking!

(Beakman seems to catch Lester urinating in plants)
Beakman: Can't you do that somewhere else?
(Lester turns round to reveal he has a water hose)
Lester: I'm sorry, Beakman. The hibiscus were looking a bit low biscus.

Phoebe: If there's no gravity in space, how do they remain seated on the toilet?
Lester: My guess is wacky glue and plenty of it.

Lester: And speaking of fixing things, I just fixed a sandwich. It doesn't have to be in space, it just has to be in my face.

Don: Do you know where we could go if we could fly?
Herb: Where?
Don: I don't know, that's why I'm asking.
