mike tyson tattoo hangover 2The man who designed Mike Tyson's distinctive tribal face tattoo is suing Warner Brothers Entertainment for copyright infringement over the use of a similar piece of body art in 'The Hangover Part II,' on the face of actor Ed Helms.

The artist, S. Victor Whitmill, claims in his lawsuit that he was never "asked for permission for, and has never consented to, the use, reproduction or creation of a derivative work based on his original tattoo," and is looking to siphon cash from the studio and delay this weekend's opening of the flick.

Those of you planning your Memorial Day festivities around a funny visit to the cineplex should have no fear -- legal experts tell PopEater the show should go on as planned.

The case hinges on the fact that the tattoo is clearly being used as a parody of Tyson's.
