Today is the 15th anniversary of the day stand-up comedian Bill Hicks died. Over in the U.K., comedy club Jongleurs in Camden held a tribute show last night. Tonight, his childhood friend Dwight Slade performs at Cap City Comedy Club in Austin, Texas, with a special screening of the 2007 tribute film, "Squeegee Your Third Eye," and a Q&A session. And as trends go, it's not surprising to see people have a dedicated Twitter hashtag for #billhicksday.
