We are having a shower for a couple at my church they eloped and i was hoping to have a funny themed but so far i have yet to find anything do you guys have any suggestions-the shower in next saturday

Did they elope somewhere fun or have any kind of honeymoon? If so, one of those places could be integrated into the theme. I'm sorry I'm not more help. Maybe this will bump your topic so that someone else will see it.

Maybe a 'house' w/window, ladder; groom at bottom; suitecase(s) in hand. I can visualize it don't know if I have explained it
This might work out much better if you made a tiered cake - ladder going from one tier to the other.....
Have you tried looking at UK wedding cakes? They have some great idea along this idea, I think.
