CINCO DE MAYO: It's tough for us to endorse yet another misunderstood cultural holiday that's long-since been appropriated by lame Americans as an excuse to drink to the point of vomiting. Then again, margaritas are delicious. The best margs we've had in the city lately were the house variety at Casa Oaxaca in Adams Morgan -- fresh ingredients and quality tequila for $7 seems like a bargain compared to the $5.50 you might pay elsewhere for a mix and the cheap stuff. Or if you're just looking for cheapo drink specials, the Rock and Roll Hotel has the most ridiculous looking party planned that we've seen: $3 coronas, "south of the border" food specials, $2 shots of tequila if you wear a lucha libre mask, and, for no apparent reason, a guitar signed by Canadian radio pop band Sum 41 will be raffled away. 7:30 p.m. to 1:30 a.m. in the upstairs bar.

READING: Arianna Huffington may run one of the most popular blogs in the world, but she also once said that print journalism would never die because "people don't want to rub marmalade all over their laptops." We have absolutely no idea what that means, but it's exactly the sort of insane just because she feels like it banter you can expect from the media mogul tonight at Politics and Prose, where she'll discuss her new book, Right is Wrong: How the Lunatic Fringe Hijacked America, Shredded the Constitution, and Made Us All Less Safe. 7 p.m.

MUSIC: The Federal Reserve Collective is back for the first Monday of the month at Iota. Tonight it's Unbuckled alums and former DCist tour diarists These United States, along with Three Stars alums Greenland. 8:30 p.m., $5.

JAZZ: Jim Levy teaches piano at GWU and gigs regularly about town. Tonight he leads his Serfs of Swing at Blues Alley for 8 and 10 p.m. sets. The group specializes in the jazz of the 1930s. Tickets are $18 + $12.50 minimum/surcharge.

MOVIE: The Goethe-Institut presents a special screening of Viva Maria!, Louis Malle's rather ridiculous 1965 musical starring Brigitte Bardot and Jeanne Moreau as two strip-tease artists who find themselves in the middle of the Mexican Revolution. 6:30 p.m., $6.
