You shouldn't scare your little siblings.
Kenny is at home with his little brother Liam and is trying to figure out something to do.
Kenny wants to play a prank on Liam.
Kenny ties a piece of string to a 5 dollar bill and dangles it in front of Liam moving it each time Liam tries to pick it up.
Kenny hides around a corner as Liam is walking around the living room and then leaps out and screams in Liam's face.
Liam realizes he's being pranked by Kenny and has a good laugh with him about it.
Liam is temporarily terrified as his heart jumps into his throat, and he dives backwards away from Kenny.
