Word has gotten back to Joanne and Aaron that there is some confusion about the line "semi-formal trampoline attire" on our wedding invitation. The trampoline combined with the fact that the wedding is being held in a venue called the "Picnic House" is leading to all kinds of problems. I mean, is this a Sunday afternoon barbeque or a wedding? Do we wear shorts and t-shirts or a suit? What's going on here?

The dress code for the wedding is straightforward, semi-formal. Don't be afraid to come decked out in your finest threads. Wear whatever you'd wear to an elegant wedding in a beautiful old park on the first day of autumn. If you don't own a suit or only have bolo ties, that's fine too. Just tuck your shirt in and come on. The ceremony will be outdoors and the reception inside.

As is prescribed in ancient Jewish tradition, there will be a trampoline at our wedding. The tradition of the wedding trampoline dates back to the Assyrian conquest of the northern tribes of Israel in 722 BCE. We bounce on the trampoline to remind ourselves of the ups and downs of marriage and of life -- that things are up, then they're down, then they're up again. The trampoline helps us remember not to get too worked up about the ups and downs, and to simply enjoy the bouncing.

We hope that you will get to the Picnic House early enough (by 3:00 pm) to bounce around on the wedding trampoline and have your airborne image captured forever on camera. "Semi-formal trampoline attire" can be interpreted in any number of ways. For some, formal duds and trampoline activity are not mutually exclusive. If you feel comfortable bouncing around in last season's satin strapless mini, we feel comfortable too! No outfit is too formal for the trampoline--it's completely your call. Perhaps you want to bring along (or wear underneath!) a pair of spandex shorts so you can bounce most freely; many savvy guests are employing this hot pants strategy. There will be a "bouncing expert" on-hand to guide, support, and suggest fun technical maneuvers. You are hereby notified that if you bounce off the trampoline and into a shrub, the bride, groom, and their parents are not libel for damages!

Did you believe the stuff about the Assyrians? It was good, right? We made it up. We're pretty certain that this is how these traditions start. Someone, for entirely personal reasons, decides that it would be really cool and fun to smash a glass underfoot after the ceremony under the huppah. Someone else decides the smashing of the glass reminds us of the destruction of the second Temple. A third person sitting in the crowd sees the smashing of the glass and decides that they want to do that at their wedding too. Bingo, you've got yourself a Jewish tradition. They've got to start somewhere.

So, seriously: The trampoline at the wedding is representative of the kallah, the bride, a.k.a. the Jojo. Traditionally, before the start of a Jewish wedding, the groom hangs out at the chusn's tisch (the groom's table) and the kallah (the bride) sits on a throne and greets all of the guests as they file in. We're reinterpreting this tradition a little bit. Rather than hanging out on a throne, which is not the Jojo's style, the kallah portion of the pre-wedding festivities will be represented, in spirit, by a trampoline.

We would be very happy to return from our honeymoon to find lots of wedding photos of our guests with their ties, dresses, hair and kids flying around and enjoying the bouncing.
