For the episode with Radioactive man, my favorite quote is: "The goggles, they do NOTHING"
ALSO, my favorite episode was the one where Sideshow Bob was trying to kill Bart, and they go into witness protection. Some quotes off the top of my head (not sure about the EXACT wording) :
(As Bart tries to sleep)
Homer: BOY, DO YOU WANT SOME BROWNIES BEFORE YOU GO TO BED??
Bart:AAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHH
Homer: Oh right, the Sideshow Bob thing... sorry
...
Homer: BOY, DO YOU WANT TO SEE MY CHAINSAW AND HOCKEY MASK??
Bart: AAAAAAAHHHHHHHHHHHH
Homes: Oh right, sorry.
Witness Protection Guy: Your name is now Homer Thompson. When I say Hello mr. Thompson, you say hello.
Homer: got it
WPG: Hello Mr. Thompson.
Homer:....
WPG: Hello Mr. Thompson.
Homer:...
...
WPG:OKAY, when i say HELLO MR THOMPSON and step on your foot, you say HELLO!!!
Homer: okay
WPG: HELLO MISTER THOMPSON (stepping on his foot quite hard)
Homer:...(to the person on his left) I think he's talking to you...
Sideshow Bob: There's no harm lying in the middle of a street... (cue parade)
(Driving to their new home)
Homer: Hey kids, Do you want to drive through that cactus patch?
Lisa: YES
Bart: YES
Bob: NO
Homer: 2 against 1
And the always funny Bob getting slapped by all the rakes
