This line from Will Ferrell in the movie Elf has turned into a bunch of t-shirts.
When my wife wanted one for a Christmas party we were going to, I decided to duplicate one of the designs by hand in Inkscape, which would then allow me to resize it as large as I wanted without distortion. I already had some iron-on transfer paper in stock.
Here's the inkscape svg file if you want to iron-on this design to your own t-shirt.
