Everybody has a relative like this. They are old. They are wrong. They are not going to change.
Maybe your grandpa tells Polish jokes in front of your Polish girlfriend. Maybe your friend's grandma says you "look like one of them damn Italians" as she puts the mashed potatoes on the table. Either way, drink that shit in. It's hilarious.
Also, if you didn't hear you can totally buy our shirts now, which I've heard make you grow in places that you would like (and need) to grow. Also, if you order one of them shits by Jan 1st, you'll get a very special, signed (or not, you tell me) print made just for this occasion. The actual image is a much higher resolution.
