This is a VeggieTales spoof of "Jingle Bells, Batman Smells".
Lyrics:
LarryBoy's in the kitchen. Thingamabob's in the hall Dr. Flurry's in the bathroom peeing on the wall.
Bane escaped the pit and he showed up too but he ate an Epic Meal and he had to take a poo. Oh!
Jingle bells, LarryBoy smells
Thingamabob laid an egg
the Larrymobile lost a wheel
and Dr. Flurry got away. Hey!
