- "These are the lousiest circus cars in the world and they're gonna make me rich!"
- —P.T. Flea
- "Wait a minute, here. They're just using the same actor over and over. What kind of a cut-rate production is this?"
- —Mack realizes that the Hamm car, the Abominable Snowplow, and the P.T. Flea car are all voiced by the same actor.
P.T. Flea is a brown bug who owns his own circus.
Circus promoter P.T. Flea has spent his life motoring around backyards; literally looking under every rock to find the next big act, like the "Flying Winnebago Brothers and their Unbreakable Trampoline" or the "Screaming Wheelies" whose tires squealed so loudly every headlight in the audience was shattered, and he's still paying off the insurance bill on that one.
P.T. Flea is painted brown, with white rims and black mirrors. He wears a black hat on his roof.
