Sherm: I always knew you were a liar, and a loser, but I never thought you'd be a THIEF! I guess I shouldn't be surprised, seems like every day you find some new way to mess up our lives, and NOW you found someone new to mess up their life too!
Followed up with...
Rigby: [On the edge of a cliff in the car, with Sherm still blaming Rigby] It doesn't matter if I ever get a big job or my G.E.D, you're STILL never gonna trust me, and that's on YOU! You're so focused on your car that you never noticed me growing up! Also, it's totally YOUR fault because you were the one driving and you weren't watching the road! NOW GIVE ME THE WHEEL!
