Actor-comedian Paritosh Tripathi has said working with Pankaj Tripathi in Anurag Basu's 'Ludo' was nothing less than a learning experience. "When I came to know I was supposed to share...screen with him, I was on cloud nine," he added. "I got to share...screen with my own inspiration. One thing I learnt from Pankaj...was how to perform natural acting," Paritosh said.
