Was the first worst proposing on a Gilligan's island style tour?
The worst that I've witnessed happened at an Olive Garden for Christmas.
Pale, frightened dude was all jittery, and I couldn't help but to peek over. Asked a waiter if that's what was going on. He said it was, and agreed to keep me posted. Turned out that whole section of the restaurant was watching that table.
Waiter brought out this huge box to their table. Dude encouraged his girl to open it, and it was filled with cake. He gave her a spoon to dig into it. She looks annoyed, but digs a bit, gets tired of it, and puts her spoon down.
Guy is a bit freaked, but he egged her into trying some more. She did, but this genius buried the ring box in the middle of this monster instead of the top. She was ticked by this process, put the spoon down and crossed her arms.
Guy gets a frantic burst of energy and starts digging on his own. He finally gets to the box, gets down on his knee and asks the question.
She looks away for what seemed like an hour (or a week to him), then held out her hand for the ring.
Blood came back to his face. He started to eat. Waiter came back to ask how things were going. She showed him the ring. Waiter turned around, clapped his hands and shouted "SHE SAID YES, EVERYBODY!!!!!"
We all applauded. They were horrified to realize that they were the night's entertainment.
Short version, too late: Don't bury the ring, kids. Just play it straight.
And, good Lord, don't propose in a cemetery.
