On the Web:
* CollegeHumor.com, a popular comedy Web site devoted to the (cough) collegiate mind, has done it again. A series of viral videos on the site features a prank war between site front page editor Streeter Seidell and senior writer Amir Blumenfeld. In the last installment (in 2007), prankster Amir gave Streeter Yankee tickets for him and his girlfriend. Amir arranged it so the JumboTron had Streeter unknowingly proposing to his girlfriend (which subsequently added to the end of their relationship). Streeter got his revenge on Amir last Tuesday during halftime of the University of Maryland-Wake Forest men's basketball game. Streeter rigged it so Amir would take a blindfolded, half-court shot at the game for a chance to win $500,000. You know the punking is coming, and it's still hilarious. See it at collegehumor.com/video:1902812.
* If you're hesitant to take a cab in an unfamiliar city, let TaxiMe (taxime.ca) be your guide. Created in Canada, the Web site has coverage that's better for our friends up north, but 16 U.S. cities are available for searching. Input start and finish addresses, and the site uses Google Maps to estimate cab fare based on the city's rates. If a city is not supported, there is a backup plan: Find out the city's taxi rate, type it in and map your route. The fare pops up, along with contact information for cab companies, which pay to be listed.
