I once took some pills which didn't do anything for six hours then suddenly hit me just as everyone was going to bed and ended up terrorising one of my mates. We'd all already wrapped this guy in cling film earlier, but I made a little fort around him with pictures off the walls then balanced loads of books and stuff on top of him, coloured in bits of his scalp with a marker pen, put toothpaste in his ear and made some toast, buttered it and balanced it on his face.
