We just had my daughter emma's 2nd birthday party. The theme was a fifties drive-in movie party. For starters, the invites were postcards for "Emma Lu's drive-in with a picture of my daughter sitting in a classic car, the backside said " hey all you grease monkeys and beauty school dropouts I'm having a drive-in movie party featuring the movie "grease" your the one that I want to come and I'm hopelessly devoted to you being their. bring a blanket in case it  isn't a warm summer night" (etc, etc.) we made classic fifties cars out of heavy duty card board boxes(complete w/flames & all) forth kids to sit in for the movie, this was no small task since we  had about 45 kids. we even made a big sign with blinking lights and arrow that said "Emma Lu's drive-in. I found those old style-paper ice cream hats (like from Johnny rockets) and printed Emma Lu's drive-in labels and stuck them on for party hats. for party favors I found these great cardboard cut-out cars (fifties classics) inside each one was a bag of classic goodies like paddle balls, jacks, pick-up sticks, finger traps, hamburger shaped yo-yos, ice cream cone bubble necklaces, tube bubbles, mini slinkys and old style candies like wax bottles, pixy stix, fun-dip, atomic fireballs and of course bazooka gum. I tied each bag with a pair of fuzzy dice and sat it inside the car boxes ( the kids loved them) for games I had a hoola-hoop contest, a drag race( blowing hotwheels across a table with a straw) and a carhop relay ( I used toy burgers, hotdogs, fries, coke bottles & ice creams on trays, the kids had to carry them with one hand to the finish and back, if they dropped any food they had to stop and put it back on their trays) for prizes I passed out blow-up guitars and saxophones ( I actually gave them out to all the participants, they were all winners) for decorations I had turquoise, pink & black balloons, paper goods and tablecloths, each table had a model car (from my dads collection), 45 records and old fashioned sundae glasses with carnations arranged like sundaes, pink then white w/ a real cherry and two straws. I sprinkled the tables with serpentines and music note confetti. I also had a big inflatable jukebox ( which looked perfect with all the guitars & saxophones around it.  a friend even brought his turquoise 55 ford and parked it right in the yard, we took photos of the kids in front of it with a Danny Zuko look-alike (a friend who looks just like john travolta in grease)  for food we served burgers and hotdogs and since fries were too big of a hassle for that many people I used chips that looked just like crinkle fries (smart & final). I rented a popcorn machine and we served milkshakes. 3 of my friends were dressed in 50's waitress dresses and wore aprons that said Emma Lu's drive-in (I printed them on iron-on transfers on the computer) they even carried trays. the cake was a full sheet frosted gray like a tray on top of it sat a hamburger shaped cake and a giant bag of fries (which were actually biscotti cookies) I used another old sundae glass and made a strawberry sundae out of mini cupcakes poked into a foam ball center with toothpicks then frosted pink and white, then a cherry and the 2 straws were 2 candles.  We even made a piñata that looked like a pair of pink fuzzy dice.  Finally after cake and presents we showed the movie Grease right there in the front yard on the  wall  of the house, we borrowed on of those projectors that you hook up to a VCR and it projected the movie beautifully right on the wall.  All of our hard work paid of when I saw all the kids sitting in their cars eating popcorn and when the movie started everyone was singing and clapping.  It was a big job since there were over 100 people altogether, but what a sight, almost everyone was dressed 50's. I ironed embroidered initials on mine and both my daughters sweaters, we all wore saddle shoes and poodle skirts ( even my 3 month old) It was a hit, everyone had a blast. surely it was one for the memory books.
