Do talent agents/agencies care if you have a weird last name?

I know that sounds dumb but someone once told me that not only do they look at the obvious; talent, experience etc. but they also take into account how your name sounds/looks. I guess what I mean by that is; the name should be "appealing". If that makes any sense. I've noticed a lot of actors have either exotic or generic names. For example, Lima, Fox, James, Vergara...I'm sure you get the point. But what happens if you have an unappealing name, one that ppl made/make jokes out of? Would this affect one's chance of getting representation or being cast in a "hollywood" movie? Is there any truth to this? I hope there isn't, that would honestly be absurd.
