Police say the man donned a range of wacky headpieces as he committed eight bank robberies in Nassau County over the course of 2 1/2 months ending July 23.
One of the banks was robbed twice.
Surveillance photos show the robber wearing a floppy white hat at one bank. At another, he accessorized with a baseball hat that had a picture of President Barack Obama on it.
And at another, he decided on a hat with a long wig attached.
Police believe it's the same robber in all the photos.
They say the stickup artist typically gives tellers a note threatening violence and demanding cash.
