If you've been humming the song or you're just a hardcore fan with all the Katy Perry gear -- down to the doll -- this is a must-do. Dress up for a chance to win $1,000 in a costume contest and party as much as you can before Halloween night even arrives. $15. 6 p.m. Dixie's Tavern, 301 East 7th St. 704-374-1700. www.kiss951.com.
