"KBBL IS GONNA GIVE ME SOMETHING STUPID!"
Bart wins a radio contest, and can choose between and elephant or the cash prize, so he picks the elephant.
So Bart and Homer go down the the radio station, but they don't have an elphant. Bart won't leave, so they toss him out. Then the radio puts on a song, but you can hear Bart yelling "Where's my elephant?" on the radio.
Abe: "Oh they're playing the elephant song!"
Jester: "I love that song. It reminds me of elephants!"
