You never know when a musical number will break out on the Dennis & Judi show. Here's proof that you always have to be ready for anything as Dennis was previewing the upcoming Quick Chek NJ Festival of Ballooning  when Judi and her backup dancers decided to groove along with the 5th Dimension's hit song 'Up, Up and Away.'
