Dean, after successfully wiping out a vampire nest, decided to celebrate at a bar where you just so happened to work. What started as a sweet conversation with a little harmless flirting somehow turned into the two of you waking up the next morning in a different state, in an unfamiliar bed, completely naked, wearing wedding rings... and handcuffed together.

And what a coincidence... the man you’re cuffed to is Dean.

God, I know this is such a cliché, but my sleep-deprived brain thinks it’s hilarious.
