In the "bringing flowers" thread someone said a unique gift would help the lady remember him.
This is absolutely spot-on!
I've had gentlemen answer the "How will she remember you?" reference question with answers which range from:
"It was raining and i helped her bring in her groceries while she held her umbrella over me." (A+)
To:
"I wore either khaki pants and a polo, or else I wore a suit." (Fail)
