A convenience store clerk in Florida is facing prison time after a nasty practical joke.

Anthony Mesa urinated in a bottle of Mountain Dew, which a customer later drank. Now Mesa faces six months in jail, after pleading no contest in court.

Mesa faced a judge on charges of tampering with a consumer product, after police in Deltona, Florida investigated that and other jokes.

According to local television station, WSBTV, they put eggs in beer cartons. And, according to authorities, Mesa urinated in the soda bottle and put it back in the refrigerator. The tainted soda was later drunk by a construction worker, who has settled a civil complaint against the store.
