One of my mates (a big 6′ 3″ guy) called Luke passed out at my flat once after a curry. For a laugh I put a Santa hat on him and we took some pictures. When it became clear he wasn’t waking up we started to take photos of him drinking larger, with the hoover in his mouth etc Until we thought it would be funny to stand him upright. By this stage we were laughing so much that when we’d got him stood up (took 4 of us, he’s a big guy) he woke up, we freaked out and dropped him as he collapsed to the floor, and then went back to sleep.
On his wedding day 2 years later his brother printed out the pictures we’d taken, which he had no recollection of.
