At my mates stag so he was so paranoid about what we were going to do that he wouldn't take much to drink. When a kissogram came in to wish him well you could see the colour coming back into his face that he could now relax as we had done our joke...Wrong, that was the bluffer, We got him blind drunk buying him doubles all night and mixing his drinks too. As he became drowsy we told him it was time for him to go home. We put him in the sleeper train from Glasgow to London.
My own night was quieter. It was a weekends camping up north with white water rafting, cliff jumping, abseiling, and canyoning. The only thing that happened to me was that as we were wild camping they put laxatives in my drink and hid the toilet paper on me!! All I can say was my a$%e was like a japanese flag by the end off the weekend. They also put some green food dye in my other drink but that never worked as my brother drank it instead and never noticed
