The clerk looks at him and says, "You must be Polish."
The guy, clearly offended, says, "Well, yes I am. But let me ask you something.
If I had asked for Italian sausage would you ask me if I was Italian?
Or if I had asked for German bratwurst, would you ask me if I was German?
Or if I asked for a kosher hot dog would you ask me if I was Jewish?
Or if I had asked for a taco would you ask if I was Mexican? Would ya, huh? Would ya?"
The clerk says, "Well, no."
"And If I'd asked for some Irish whiskey, would you ask if I was Irish?"
"Well, I probably wouldn't."
"Well, all right then, why did you ask me if I'm Polish just because I ask for Polish sausage?"
The clerk replies, "Because you're at Home Depot."
(p.s. Don't yell at me, my father is Polish.)
