A man wakes up the morning after a party with a pounding hangover and only vague memories of what happened the previous night. The only relatively clear image in his mind is that the house where the party was had a golden toilet. This seems so unlikely that he dismisses it as just his imagination, but the image won't go away and he finally decides that the only way to settle the matter is to go back to the house and check. The problem is that he can't remember the address - he doesn't even know the name of the people who hosted the party as he was having a drink in the pub when he got chatting to some strangers who were on their way to it, and they invited him along. The only clue is that the house was within walking distance of the pub, so he goes there and starts walking the streets until he finally finds one that looks vaguely familiar. He's about to go up to the door when he realises that asking the householder if he has a golden toilet is going to make him look really stupid, so he comes up with a plan to get himself invited into the house, then ask to use the toilet and see for himself. So he goes up to the door and rings the bell. After a few moments the door is opened by a man who looks as if he's just got out of bed. Before the visitor can speak, the householder grabs him by the lapels and shouts, "You! You're the b*****d who shat in my tuba!"
