Need instructional videos of how to dance at clubs/parties?

Hey so I am 18 and male and am finding that life now includes many parties and nights out at town at clubs and stuff. Thing is I have no idea how to really dance and feel kind of awkward on the dancefloor because of so. What I need is a good set of instructional videos of some basic dance moves that will make me appear less awkward. Videos preferable so I can play them off my pc or on the TV and practice. Not really willing to pay for the videos unless this cant be avoided. Help will be greatly appreciated.
