You know those giant inflatable things that you usually see on car lots? Like the giant monkeys and whatnot?
I just had the idea to create a giant inflatable Nativity scene in that style, to sell to megachurches. Here's the kicker: as part of the design, the giant baby Jesus inflates separately, so you don't have to inflate him until December 25th.
...I'm so going to Hell for this idea. But you can't tell me it won't sell.
EDIT: In the course of market research, I stumbled upon
this glorious website!
