This Back To The Future shirt shows what an advertisement for the Marty McFly Time Travel Agency would look like. Of course, this is a t-shirt for a fan of the 1985 classic. But, just imagine having Marty McFly take you back in time to make out with your own mother. Or having him take you back to the 1980s to warn everybody not to waste their money on perms, acid-washed jeans and Koosh Balls. The possibilities…Great Scott!
