Kelly (while looking at Artie the lizard):
Aww, he looks so peaceful when he sleeps.

Lisa:
Oh, please. You're going gaga over something that burps bugs.

Jessie:
I think he looks a little pale.

Kelly:
Maybe he's sick.

Zack:
Why would he be sick? (Screech walks over) Hey, Screech, come here. Take a peek at Artie. Does he look any different to you?

Screech:
No.

Zack:
See?

Screech:
Except for the fact that he's dead.
