This 80sTees.com exclusive Christmas Vacation t-shirt shows Aunt Bethany's famous lime Jell-O mold holiday dessert. The shirt includes Eddie's quote, "I Don't Know About The Cat...But I Sure Am Enjoyin It". When the Griswolds invited family to their house for Christmas, Aunt Bethany and Uncle Lewis arrived with a box that was leaking Aunt Bethany's lime Jell-O mold. It was a holiday dessert that Eddie couldn't get enough of. Whenever anyone sits down to eat this holiday dessert, they must first remember to say grace. The blessing!
