Midnight Spank (formerly 'G4 Late Nights' and Barbed Wire Biscuit) was the former name of a late-night block shown on G4. This block was originally based on G4's recent venture to Williams Street Studios, pioneers of the Adult Swim block on Cartoon Network. G4 Late Nights was made originally to offer the similar content like that of Adult Swim. The block offered syndicated content targeted towards the 18-25 male demographic. Midnight Spank aired mostly acquired programming, with occasional original programming.
