A wedding need neither be bland nor short to be cheap; hook-ups, dance floors, embarrassment and kicking it until 4am don't require that much money.
It'd be nice to think that this was intended and took as a spoof of the conspicuous consumption that big weddings are, but I suspect that, considering the target audience, there was a lot of nodding all around.
But the part friends & family still talk about years later is, "Hey, remember when your German Shepherd was your ring-bearer at your wedding, and you sent her running down the aisle? That was great!"
Doesn't take money to be entertaining.
