This is just about the most horrifying reason for BAD GAS I've ever heard of.
A 67-year-old guy in Nong Khai, Thailand went to the doctor over the weekend after three weeks where he couldn't stop passing gas.
And it turned out the reason was . . . he had a 59-FOOT TAPEWORM in his body. The doctors think he got it from eating raw beef.
Believe it or not, that five-foot tapeworm ISN'T the longest one that's ever been pulled out of a person. The record is82 feet, which got pulled out of a guy in India.
