Snooki's Boozy Faceplant Right Before the Arrest

7/30/2010 5:54 PM PDT BY TMZ STAFF
TMZ has obtained footage -- pretty painful footage -- showing a wobbly Snooki trying to get on a bicycle right  before she was arrested earlier today ... and as you can imagine ... gravity wins.

Some time after the faceplant ... Snooki did something to attract the attention of Seaside Heights police ... who eventually arrested the "Jersey Shore" star for disorderly conduct.
