What have you done that just knocked a women's socks off?

The thing wasn't something I said...but something I did. I was dating this girl when I was in college. She was living in Fort Worth and I was in College Station. We had started dating a couple of months before. The day she was driving down for the weekend, I took my suit over to my roommate's girlfriend's place (in the same complex...convenient, eh?). The next day close to dinnertime I told my girlfriend that I needed to go get money from an ATM for dinner and that she should just chill on the couch and watch some TV and I'd be back in a few. I went to my roommate's girfriend's place and changed out of my shorts and T shirt into my suit. I then went to the store and pulsed money out and bought flowers. I then went back to my place. I knocked on my own front door...my girlfriend opened the door. I handed her the flowers and asked if she'd like to have dinner with me that night. She was totally speechless. She just hugged me as close as she could for a couple of minutes. She finally said that she'd love to have dinner so I took her to a romantic dinner at a dimly lit, moderately expensive place. To this day I haven't been able to think of a way to top that performance.
