Helium strikes again. The funniest of all gasses broke the heart of Londoner and jokester Lefkos Hajji, who had concealed a $12,000 engagement ring in a balloon full of the stuff. His plan? To hand his intended, Leanne, a pin so she could pop the balloon as he popped the question.

Sadly, just as Hajji exited the jewelers, a gust of wind snatched the balloon from his hand allowing wicked helium to carry his rock into the sky. A frantic two-hour car chase ensued, man vs. balloon, but eventually the helium made a clean getaway.

The English seem to have a particular problem with helium. In 2007, Calum McFadyen, at his four-year-old son's behest, tied his wedding ring to a Thomas the Tank Engine helium balloon while playing in the house. He forgot about it until his son opened the front door and the balloon made a mad, successful, dash for freedom. His dad was particularly miffed that his son stood in the doorway gleefully waving goodbye to his balloon.

The lesson? Never mix fine jewelry and helium: the cops don't pay attention to callers with high, squeaky voices, no matter how desperately you need their helicopter.
