Someone is using Craigslist "missed connections" to track down a commuter on the 6 train, but the only thing the ad seems interested in connecting is some Beano to this dude's mouth. Yes, there's a farter on the loose in New York's subway tunnels, and this man's butthole is apparently not shy about letting loose in a crowded train car. 

The ad really says it all:
