Talk show host Jimmy Kimmel has a well-established penchant for playing mean pranks on kids — usually by proxy. There was the infamous Halloween treat trick, the notorious Nasty Christmas gag, and the hilariously underhanded "Waking Kids Up for School in Summer."

Yahoo beat analyst expectations for its first-quarter revenues by $30 million, $1.35 billion to $1.32 billion. Its net income, at $542 million, was considerably higher than Wall Street had hoped for, too. But $401 million of that profit came from a noncash gain, Yahoo's take from Alibaba.com's initial public offering, from which Yahoo profited because it owns 39 percent of Alibaba Group, Alibaba.com's parent company. Investors have taken this caveat into account, bidding Yahoo's stock slightly down in after-hours trading. Commenter WagCurious wants to tar and feather Yahoo CFO Blake Jorgensen for including these gains in Yahoo's quarterly revenues. But one-time gains like this are a well-understood phenomenon, and there's nothing unusual about Yahoo's treatment of it. If nothing else, Wall Street understands making money from buying and selling pieces of companies.
