It was you, all right.

The Lineup:

"Promises", a Canadian-based pop group that made waves in the late 1970s with their hit "Baby, It's You." The group is made up of Leslie, Jed, and Benny. And they're all siblings!

Fart Factor:
7 out of 10. All are stoic against the stink. They were raised right.
Leslie later went on to record two songs for the 2001 Dennis Hopper movie "Choke." The two brothers wound up dancing jigs at farmers markets.

Most Likely Fart Suspect:
Contrary to popular belief, overalls don't cover everything. Jed did it.
