Sandy then lifts a barbell with two anchors attached to it, the audience is very impressed and as they are cheering Larry lifts up the bleachers with the observers still seated there.
SpongeBob, still sunken in the sand feels that they are now just showing off. He burrows his way to a nearby camper and asks if he can borrow a couple marshmallows. He attaches the marshmallows to his stick from earlier and tries to lift it but with no success. Determined, he lifts the stick with all his might and rips his pants in the process. The audience then laughs. SpongeBob scuttles away embarrassed. Sandy, assuming SpongeBob did it on purpose then comments "ain't he the funniest little sponge ya ever saw?!". SpongeBob then grins and gets an idea.

Now playing frisbee, SpongeBob asks Sandy to throw the frisbee to him. She does so and SpongeBob lowers his hand casually allowing the frisbee to hit them in the face. Sandy then walks over and asks SpongeBob if he's all right. SpongeBob replies "I guess so. Except I ripped my pants!" Everybody laughs.

SpongeBob asks the lifeguard to come closer and tells him that he needs a tailor because he ripped his pants. Everybody then walks off upset and Sandy says "that wasn't funny SpongeBob y'all had me worried sick!".
He tries to make the joke work again by saying "not ripped pants, pants ripped off" but he then realizes that everybody is gone (including his pants). He then asks "am I the biggest loser on the beach?" and is soon joined by three other unfortunate citizens and they begin to sing the song "Ripped Pants".
Sandy, realizing that SpongeBob's song is true tells him "your song is true. If y'all want to be my friend just be yourself."
Larry then asks SpongeBob to sign his pants and when SpongeBob bends over to do so, his underpants rip off and he is embarrassed once again.
