"I'm gonna fight you!" is a famous phrase uttered by Adam right before he fought his dad.
In 1998, Liam used a tape recorder to record a fight with his dad. He showed it to Adam, and Adam borrowed the tape for a while. A couple weeks later, Adam told Liam that he had something to show him on the tape. He gave the tape back to Liam, and Liam started to listen to it. The tape went something like this:
Adam: I was inspired by Liam fighting his dad, so I decided to make my own fighting tape. Here's how it went.
Adam: "I'M GONNA FIGHT YOU!"
Right after Adam said this, the sound of him hitting Al can be heard in the background for the next 5 minutes.
