This sounds like something out of Hitchhiker's Guide to the Galaxy, especially the last line.
Robber holds up bank with bunch of flowers
The thief approached the cashier's window in the United States with a large bouquet of flowers and handing over a hold-up note.
Police told The New York Post they were examining a large bunch of blooms - yellow chrysanthemums, orange and red daisies, and gladiola buds, among others flowers - used by the man in the robbery last week.
A security camera photo published by the police showed the suspect standing at the cashier's window holding the bouquet while handing over the note, which reportedly read: "Give me all your hundreds, fifties, don't be a hero."
The man fled the scene after the teller handed over $440 (£288).
The New York Post reported that it was the second known bank heist by the suspect, who last week robbed a different New York bank armed with a potted houseplant.
