Riding in a Uber can be uncomfortable enough, what with the confusion over tipping, journalist-stalking, and hammer attacks. Add to those indignities the prospect of having to ride in a car driven by your ex-boy or girlfriend, and you've got Second City's idea for Uber's newest service, Uberex.

"We offer a quick, comfortable, and personal ride that only an ex can deliver," which is exactly the nightmare it sounds like it could be. "Using our state-of-the art social algorithms and your sister, Uberex can predictively target both your pick up and destination points."

Of course, given how small SF is, I'm kind of surprised that this farcically-intended "service" hasn't already happened in real life. Surely there's someone out there who's gotten picked up by/picked up an ex via Uber, Lyft, Sidecar, etc? If so, tell me all about it! (No Penthouse Letters please, eeew.)
