Weird Al was joking on one of the music shows a few years back about how he was "just" a one-hit wonder. Although he was had dozens of top 40 songs, the only one to crack the top 10 was "White and Nerdy", his parody of "Ridin' Dirty" that hit 8 on the charts several years ago, technically making him a one-hit wonder by the standard definition of "an artist or group with only one top ten song". (of course he was in good company, because under that definition so was "The Grateful Dead", their only top ten song being "Touch of Grey")
Lol! I guess now he is a bonafide artist and not just a "flash in the pan" one-hit wonder....
