"Happy 77th trip around the sun, Tim Matheson! It seems like just yesterday you were charming us as Otter in 'Animal House', but here you are, another year wiser and still stealing hearts. As you blow out the candles (and the hot air from all your adoring fans), know that your talent and charisma have only gotten better with age. Cheers to many more years of laughter and success. Happy birthday, you old but fabulous chap! #77goingon17"
