"They said I could never teach a llama to drive!"— Christopher "Bing" Bingham
The man in the fourth movie announces the robbery is YouTube vlogger and creepy guy Jack "Jacksfilms" Douglass. Perhaps not as known, and it'a a little hard to hear, but still, hey, where did he come from?
Also in the fourth movie, the robber who gets held up by a finger gun and the guy holding the finger gun are voiced by Awesome Series creator Egoraptor.
