Dr. Fred: Leaping labrats!
Bernard: Dr.Fred?
Dr. Fred: What have you done this time you meddling milquetoast?
Dr. Fred (cont'd): Now Purple Tentacle is free to use his evil mutant powers to take over the world and enslave all humanity!
Bernard: OOps.
I actually remember that one quoted in the IMDb entry. :D
Bernard: How's Dr. Fred?
Nurse Edna: He's doing better ever since he stopped sleepwalking.
Bernard: How did he stop sleepwalking?
Nurse Edna: He stopped sleeping.
:D

Dr. Fred - Step one. Find plans.
Step two. Save world.
Step three... Get out of my house!
... Let's get cracking!
