"Mr. Showtime," David Scott, is the pinnacle of entertainment and hilarity all held together by awesome hair products. An electrifying entertainer who does so much more then stand behind a microphone and tell jokes. Comedy, Music, Impressions, and the Worlds Most Dangerous bit in Comedy. Oh did we mention David is also the Guinness World Record Holder for Longest Stand-Up Comedy Show by an Individual? Well he is by performing for 40 hours and 8 minutes.
