Herschel is kind of the stereotypical name for the old Jewish guy in jokes. Like the schlemiel, I guess they call it, the guy who's kind of the born loser.
There's also Uncle
Herschel, the quasi-mascot of the Cracker Barrel restaurant chain. A couple dishes on the menu have his name attached to them.
In short, no, I don't like it at all. It's unattractive in sound and incredibly dated.
