It was quite the surprise for Bob to have Bart and Lisa Simpson burst through the door.
"Sideshow Bob," yelled Lisa, "drop that knife and give back our dad!...Huh?"
Bob didn't blame the kids for looking so confused, as it was rather out-of-character for Bob to make sculptures of Krusty, or be willingly around him at all. Bob was grateful when Krusty provided his alibi, but wished that he'd left out a few details.
"Then explain THIS!" said Lisa, holding up the "SB" keychain.
Bob took a look at the keychain. "It was nice of you to think of me. However, 'S.B.' could be anyone." Bob had really come to expect more from the Simpson kids, even Bart. Their cluelessness here was quite disappointing. He began to list other 'S.B's:
"Scott Baio, the Sultan of Brunei, the former Polish secret police: the Sluzba Bezpieczenstwa...or Selma Bouvier."
Lisa quirked an eyebrow. "Aunt Selma?" She glanced at Bart, who shrugged. "I know that she and Aunt Patty hate Dad, but I don't think they'd sink low enough to kidnap him."
"Well, can you think of anyone else?" Bob asked coolly.
For once, Lisa had nothing to say.
"Hello?" Bart waved his hand in front of Lisa's face. "Come back to Earth, Lis!"
Lisa shook her head. "Come on, Bart, let's go! If Bob's right, Aunt Patty and Aunt Selma have a lot to answer for!"
"Yeah," Bart said as if to agree, though he really wasn't sure what that expression meant.
Bob moved the two young Simpsons towards the door (he had to remember to put down the knife, first). "As much as I'd like to come with you and see how this all turns out, I can't be out in the open at this time."
He regretted saying that when Bart got a sneaky look in his eyes. "Ten bucks if you don't want us to snitch."
Bob's gaze drifted back over to his knife, thinking of another way that would stop the kids from snitching.
"You're lucky that I'm in a charitable mood today, Bart," Bob sighed, handing over the money. "Just leave now."
Bart waved to Krusty and Mr. Teeny, who were now the ones appearing confused by all of this. "Bye, Krusty!"
"Yeah, bye, kid," Krusty muttered, paying more attention to the cigar that he was lighting.
