I proposed to my boyfriend at LEGOLAND with a LEGO version of us when we first met (me dressed as Amy Pond and him in a top hat) in front of a LEGO TARDIS. I made him use a sonic screwdriver to get the ring out. =)
My fiancé and I decided to get other small, silly, surprise gifts for our rehearsal dinner. When we opened our gifts, I couldn't believe it! We had both bought each other identical Sonic Screwdriver pens! Of course we used them to sign the marriage license!
