hmmm, well I have had some strange experiences, but I don't know if I would call them creepy per se. I agree that rude or explicit comments are unacceptable. I HATE people invading my space since I have had an attempted rape. But specifically...
1. A guy serenaded me down the street singing My Girl. However, I think it was because he wanted money.
2. A guy asked JJ if he could dance with me. Sounds normal if we were in a dance club, but we were walking down the street.
3. A guy asked me if I knew that inter-racial dating was the cool thing to do.
4. When I worked at the grocery store a man bought a rose and said it was for me because a beautiful rose should belong to a beautiful girl.
5. A guy I dated once was actually a psycho and used to sneak into the grocery store and send love letters down the belt of the register and leave.
The letter was the only one that seemed creepy to me because I knew him and he was pretty weird. I don't know if those are example the OP wanted, but thought I would share.
PS I typically don't use that many smilies, but I thought they would express the mood better...
