If you didn't get enough laughs during the CanWest Comedy Fest a few weeks ago, there are more than enough going around this weekend, too. Not only are Dennis Miller and Gilbert Gottfried here, but Yuk Yuk's Comedy Club is hosting the fabulous Mike MacDonald for its third anniversary celebration from Thursday to Saturday (October 12 to 14), and Mr. Warmth, Don Rickles, is at the River Rock Show Theatre on Saturday (October 14). Plan it right and you can hit them all: Gottfried on Thursday, Miller on Friday, Rickles on Saturday, then zip on back downtown for the late show at Yuks with MacDonald. How do you choose among four of the best? You don't, that's how.
