This is a very interesting episode. When Drake and Josh went to a Padres baseball game back in 1997 before Josh's dad and Drake's mom were married and got together, Josh assumed that Drake thumped him in the head and Drake assumed Josh attacked him for no reason so Lenny Spodnick, the guy who sells foam fingers, called the cops on them and they didn't realize that when Drake and Josh got together. When Josh's dad talked him into going to the Padres game, Josh was complaining that he wont go there again because of what happened 8 years back. When Drake's mom asked him if he was at the Padres game 8 years back, Drake had the same problem too and when he was complaining, Drake and Josh found out that it was each other and they were fighting and bickering. Drake showed Josh the foam finger and Josh ripped the finger off and after that, they had a big fight so Drake moved out of his room with Josh. Drake had to find somewhere else to sleep like the living room, bathroom, or Megan's room. Drake could've stay in a hotel to get away from Josh. So Megan helped by calling the stadium to invite Lenny Spodnick, the guy who sells foam fingers, to their house and he can tell what really happened 8 years back. When Lenny told the story, Drake and Josh found out Megan started the fight by throwing a cookie at Josh's head. When Lenny sold bobble heads, Drake and Josh were fighting for it just like the foam finger so their dad took the fight outside. A few days later, Drake decided to move back to the room with Josh and he realized that he and Josh acted stupid and also jerks.
