The man who sings the Yahoo! yodel is suing Yahoo! for $5 million. He says that they paid him $590 for the rights to use the now-famous yodel for one commercial only, then they've continued to use it in thousands of subsequent TV ads without his permission. (After the lawsuit is resolved, will he be singing "Woo-hoo-o-o-o-o...!" or "Boo-hoo-o-o-o-o..."?)
