User Cruizn63, who is Mexican (or American of Mexican descent I think) has been wearing this one since forever:
For the 2014 World Cup I made myself this one when Cruizn and I were teaming up in a "World Cup Bad Poster Draft Thread":
Somebody asked me if I could shop Messi's head onto Daffy's body and place it in front of an Argentinian flag.
So I did:
People seemed to like the idea and asked me for other combos (I lost count, but I'd estimate I made around 60-80 of these over the years until now).
The rest, as they say, is history.
If you want one for yourself, let me know.
