SAN FRANCISCO (CBS SF/AP) – Putting a new test to the adage that brevity is the soul of wit, Comedy Central is partnering with San Francisco-based Twitter for a comedy festival played out in 140 characters and 6-second videos.

The Viacom Inc.-owned network said Sunday that the festival with the hashtag “#ComedyFest” will debut April 29. Over five days, comedians will tweet jokes and post videos with the recently launched video app Vine, which limits footage to 6 seconds.
