This 80sTees.com exclusive Christmas Vacation t-shirt is designed to look like an ugly knit sweater with images of falling snow, Christmas trees and the quote Why Is The Carpet All Wet Todd? While hanging Christmas lights on his house, Clark Griswold fell, grabbed on to his gutter, and sent ice flying through his neighbor's window. Later, Clark's neighbor, Margo saw the broken window, found melted ice on her carpet, and asked her husband, "Why is the carpet all wet Todd?". Todd responded by saying, "I don't know Margo".
