Officials with the University of Kansas Cancer Center are hoping someone with a heart returns a stolen colon.

A $1,000 reward is being offered for information leading to the return of a giant 10-foot long, 150-pound inflatable human colon, officials said Friday.

The fake intestine is worth $4,000 and was stored in a plastic bin and poached from the bed of a parked pickup truck in a Kansas City neighborhood. It was in the city for a Saturday walk/run event, the Kansas City Star reported.

“Colorectal cancer screening is the most powerful weapon we have against colorectal cancer,” said John Ashcraft, a surgical oncologist at the center. “Colon cancer is a tough subject for many to talk about and the giant, 150-pound, 10-foot-long inflatable colon is a great conversation starter.”

Stacie Moody, the local events coordinator for Get Your Rear in Gear-Kansas City, which raises colon cancer awareness, said whoever took the item probably ditched it.

"There's not much of a black market for a giant inflatable colon."
