Ha. I work at Walmart and I have to drive those 'mobility scooters' around all the time.
Check out this episode of American Dad.
http://www.watchcartoononline.com/american-dad-season-5-episode-87-%E2%80%93-raptures-delightIt's about the Rapture in the book of Revelation where Stan gets left behind to face the 7 year tribulation. The second half of the episode takes place in a post appocalyptic world where Stan becomes a mercenary and trys to rescue his wife with the help of mercenary Jesus. The whole thing is done in the style of a bad ass cheesey 80's style action movie.
