Geeky marriage proposal has awesome surprise Star Trek guest star

We've seen a ton of geeky sci-fi weddings and marriage proposals over the years, but none with as good a surprise guest star or punch line as this one.

At Wizard World Chicago Comic Con last week, a guy got down on one knee to propose, and while you can't quite hear what he had to say, you can tell his girlfriend was eating it up.

The surprise ending of the 40-second clip is what makes it all worthwhile, and we don't intend to spoil it for you by telling you who pops up. So just check it out!

Engaged, indeed!
