DIAL M-A-C-E-O: You know how some people are so funny (Steve Carell, Ellen DeGeneres) that just looking at them makes you laugh? Well, that's kind of how Maceo makes us feel, but instead of making us laugh, he makes us get funky. He's played with everyone who matters—from James Brown to Prince—and he's here tonight and for the rest of the weekend to bring the funk to you. How lucky you are!

7:30 p.m. // Dimitriou's Jazz Alley // $45

SHAKE THE SHACK: Speaking of weekend activities that kick off today, the Tractor has KEXP's Shake the Shack 21st Annual Rockabilly Ball. Tonight's line-up includes Slim Sandy, Texas Steve and the Git Gone Trio, and more. Even if you don't know much about Rockabilly, you should make like a good Seattle music fan and trust KEXP. A full line-up is available at MySpace.

8 p.m. // Tractor Tavern // $18/day, $50 for a 3-day pass

THE PHILOSOPHY GUYS: We like philosophy, and we like silly jokes. So, we have to give some mad props to Thomas Cathcart and Daniel Klein for bringing the two together. Again! They'll be at Elliott Bay Books tonight to read from their books Plato and Platypus Walk into a Bar: Understanding Philosophy Through Jokes and Aristotle and Aardvark Go to Washington. Fun!

6 p.m. // Elliott Bay Books // Free
