Bart's Homework

Bart's Homework is the second Butterfinger BB's commercial. It first aired sometime in 1992.

Plot
Lisa asks Bart a subtraction problem; she uses fifteen of his Butterfinger BB's to demonstrate. Lisa then asks Bart how many he would have left if she snagged five of them. Bart angrily eyes Lisa, who wants some of his BB's, "One less sister!" He then snags his BB's back from her.

After the announcer's interlude, Bart, hogging his BB's, says his tagline, "Nobody better lay a finger on my Butterfinger!". He then accidentally drops a BB, which Maggie takes from him.
