I don't know if they didn't do a sound check of if the performers were holding the mic too close to their hands but I couldn't hear a big portion of the jokes. The sound coming from the speakers was very muffled. I thought I was beginning to have a hearing issue until my friend who was with me also said he could t hear alot of the jokes either. Karlous and DC said we were a "weird crowd." Were not weird but philly is notoriously known as a tough crowd. We don't laugh at every thing. You can't expect us to die of laughter from jokes you get up there and freestyle. Conjure up some real jokes!
