Happy 78th birthday to the one and only Tim Matheson! On this special day, we celebrate not only your impressive acting career and charming smile, but also the fact that you were born on the most exciting night of the year - Dec 31st! Cheers to another spin around the sun and may your year be filled with love, joy, and laughter (and maybe a little bit of mischief). Keep shining and making us all fall in love with you, just as you did in Animal House. Happy birthday!
