Ronnie "Woo Woo" Wickers (born October 31, 1941) is a longtime Chicago Cubs fan and local celebrity in the Chicago area. He is known to Wrigley Field visitors for his idiosyncratic cheers at baseball games, generally punctuated with an exclamatory "Woo!" (e.g.,  "Cubs, woo!
Big-Z, woo! Zambrano, woo! Cubs, woo!")
