If you're sick of Hurricane Sandy footage, check this video out:  A drunk guy wearing a "Ghostbusters" costume was arrested in Canada . . . after he climbed onto the roof of a POLICE CAR, then backflipped OVER a cop.

--He somehow managed to LAND it . . . then immediately got thrown up against the car and handcuffed.  (--TMZ has the video.  Search for "Ghostbuster Arrested for Cop Car Stunt."  WARNING:  One of the cops calls him a "smart*ss.")
