My friend and i are both married. We are planning to take a camping trip soon. every year we do this, we always play jokes on each other. One year we had another couple with us and my gal friend and i switched campers in the early am so i was with her husband and she with mine. when the other couple came out of their camper later that morning we all came out and they looked so confused. and yes drinking was involved so they thought we slept with the wrong husband and that something else happened too. we told them later it was a joke and they just about fell over cause they were laughing so hard. this year we want to play one on our husbands but they cant know about it. Any fun ideas????
