I have a feeling the decrepit imbecile doesn't realize that in American football, Canadian football, and hockey, the uniform shirt is called a jersey.
Because apparently he thinks he's in England. Musta been the picture of Her Maj on the wall that got him all confused.
If anyone is a decrepit imbecile it's you...…………….I know what a jersey is Asshole, I have 3 kids who were all involved in team sports, but the term "shirt" or "sweater" can be used interchangeably. Smarten up!
