Bubba J asks Achmed if his flaming-skull car is a "hybrid" vehicle. Jeff Dunham himself owned a Toyota Prius, and in the subsequent movie "Achmed Saves America", Carl Zimmer drives one of these same type of cars, as well.
Achmed's son A.J. is portrayed as the exact opposite of his irritable contemptuous murderous papa, both in personality and mindset, but with a humorous "visual pun" twist: while Achmed hates most humans as being "infidels" whom he wants to "keel", the passive peaceable soft-spoken A.J. is totally a "lover of men", but in a literal sense, since he views males as attractive and romantically desirable.
