Greg tries to punch Rodrick at a roller rink, but misses and lands face-first on a birthday cake. We then see a cartoon version of young girls hitting Greg for ruining their party.
Rodrick has Greg and Rowley ride in the back of his band's van, where there are no seats. The two boys are then bounced around hard during the drive (played for laughs), with Rowley's clothed butt landing on Greg's face.
We see an online video of an older woman falling off a stage to a table, but then profiting from selling her resultant fame. Greg and Rowley try to make money the same way, hoping to capture Rowley falling backwards from being seated in a chair, but that doesn't work. However, Rowley (with underwear on his head, put there by Greg) later accidentally sits on a ball of foil with small wooden spikes coming out of it.
As a result of Rodrick embarrassing Greg in church, Greg jumps on Rodrick and tackles him to the floor
We see a flashback to Rowley jumping up and down on a bed and then falling off (we don't see the impact on the floor).
After getting his diary back from his brother in a senior citizens center, but realizing he's only in his underwear, Greg darts into a bathroom, not realizing it's the women's room. He then peers out through the crack of the stall door, only to see a woman's eyeball right there. He then hits the floor and tries to scramble away, with one woman hitting him with her purse, while another grabs him once he's standing, but he manages to get away from her and others who've mistakenly grabbed and are holding another woman in a headlock (all played for laughs).
Two boys watch a horror film and there is a picture of a man with no foot. In the horror film and women gets a toe shoved up her nose, it does not really look like it.
