Those are some friends
Besides Avery and Max, you gotta admit Jay Mohr and the student doctor are great friends. I mean, they agree to help kidnap a mobster and mutiliate him because they were tricked into believing their buddy's sister/other buddy's girlfriend was kidnapped. I don't think my mates would do the same for me if my sister was kidnapped, even if it were just an act.
As a side note, were they just going to let Charlie go after the kidnapping matter was resolved?
