Yeah, I'm not so sure this is a good idea. I've stopped doing it.
On one level, it's "I'm going to be self-deprecatorily polite and warn you about my amusing little foibles".
On another, it's "I don't give a fuck about you, and you know what? I'm going to tell you that, right from the off."
I now save this for when I really, really want them to know the latter.
Eh, I don't do it professionally, and frankly, I just don't give a fuck otherwise. They might as well know that about me from the start.
On the other hand, most people seem to be relieved and commiserate. Sometimes it actually leads to a conversation instead of me just wandering off having already forgotten the name.
