It's funny that a guy that looks like Phoenix Wright is the exact opposite of Phoenix Wright. Unlike Phoenix Wright, this guy:
1. Is a prosecutor (of sorts?)
2. Knows exactly what he's saying 99% of the time (since Phoenix sometimes has no idea what he's doing)
3. Is easily attracted to "bouncy things" (since Phoenix doesn't easily get attracted to people as a lawyer)
All of that is what makes this animation funny.
