What episodes of Gilmore Girls are these quotes from?

I would like to know the season and the episodes that these quotes are from:

Luke: I'm just having a bad day.

Lorelai: zzz.

Luke: what?

Lore: Dayzzz. You've been sitting around here barking at people for days!

Luke: I do not bark.

Lore: Yes, Cujo, you do.

Luke: I'm always like this.

Lore: No Benji, you're not.

Luke: I'll be fine tomorrow.

Lore: Really Lassie? Why is that?

Emily: You should really eat more greens, lorelai.

Lorelai: I plan to eat a five dollar bill later.

Thanks!!
