Everyone piles in the car and you drive down the road until you see this dirty bum hitchhiking. So you pick him up.  He throws his duffel bag in the back and you ask him where to. He says he just needs to go down the road to the mall.  When you get there he gets out and you drive away.  OOPS! He left his duffel bag in the back.  You drive back but he's already gone so you take everyone with you into the mall.  There you have a table set up with balloons and confetti (the works!) and you open the bag to find DINNER and SPARKING CIDER!    Of course, this takes a little prior planning like finding someone to play the bum, set up at the mall with permission, etc. but it's one your friends will never forget.  This is a great SURPRISE PARTY idea too.
