You should have rebounded to,"No, no. Your last name. I don't remember it."

ive done this! someone in my drama class that ive only really spoken with in the class, gave me his cell number... i put his first name in and then i was like... 'how do you spell your last name?' no knowing what it was...he was like 'k-i-n-g, how many ways do YOU know to spell King?' it was embarassing!

there's nothing wrong with asking someone what their name is, as long as do it right at the beginning of the conversation

I do that a lot. Unf, maybe I should stop. I like #1's idea.

This doesn't work too well with white people, unfortunately.

That's not too big a deal. Don't worry, he might spell Rob a different way--Robb, Rhob...Ok, not the second one, but you really can't be sure =)

Hey, I'm next to the little anime dude. Awesome!

Always be honest when it comes to forgetting someone's name. Trust me.

When he says R-O-B, you can just smile and say, "So it's one b? Just making sure." Or if he says "Rob," you can ask if it's one or two. There's usually a way out of stupid mistakes.

I've heard a story exactly like this before, except the guy's name was b-o-b. :|
