Wow, so #tomandsarahswedding was one to remember. Usually when strangers get themselves involved during a wedding, it's to say "Congratulations", or "he's a lucky man" or "DON'T DO IT!" and therefore you just smile, nod, and move swiftly away.

We're not sure how the below went unnoticed by the internet for the last few days, but thanks to Cosmo for bringing these moments of marital bliss to our attention.

Wait, there's more via the wonder of Facebook...

Now that's a day to remember.
