If something seemed off about Sam Atherton when his 'American Idol' aired on Wednesday night (Jan. 15), it's because he actually has a pretty checkered past.

In 2010, Atherton was allegedly caught masturbating in a frozen lemonade truck.

Even worse? There were kids around because he was supposed to be serving frozen lemonade to churchgoers and their families.

No. Just no.

Atherton was taken in by police for "open and gross lewdness" when a witness caught him with his pants literally down, but Atherton claimed he was just scratching his foot.

He was ultimately convicted for "two counts of lewdness" and given two years of probation.
