Until they were gunned down by police, outlaws Bonnie and Clyde (Bonnie Parker and Clyde Barrow) were notoriously successful bank robbers during the Great Depression of the 1930's.

But Ronnie and Clyde? They're just a mess.

On last night's 'Saturday Night Live,' returning musical guest Rihanna reteamed with Andy Samberg for a new digital short about the bad-ass female gangster Clyde and her way too soft-spoken partner in crime, Shy Ronnie (the messy, anxious, socially inept nerd featured during a previous 'SNL' episode with Rihanna).

The hip-hop music video features confident vocals by the Grammy winner, some very mismatched weapons, completely baffled bank robbery victims, vintage wardrobe inspired by the 1967 film 'Bonnie and Clyde,' plus a few hilariously naughty moments (Shy Ronnie is easily aroused, and loves hardcore rap solos!). And don't miss sexy Rihanna escaping the scene of the crime with sexy bystander Jon Hamm (the 'Mad Men' star was host of last night's episode).
