Happy birthday to the one and only John Ratzenberger! Can you believe he turned 78 years old on April 6th? It seems like just yesterday he was cracking jokes as Cliff Clavin on "Cheers." Wishing you all the joy, laughter, and success in the world on this special day. Keep on being the talented and hilarious guy we all know and love. Cheers to many more years of awesomeness!
