Blipzers!

Well, I tried, tactfully, to tell 46 that this was rather unsubtle, but he was adamant. "Grits," he sniffed, "I am a Blipzer" (he means that he is related to Schnauzers, the same breed as his cousins Jefferson, Otto and Hilda), "and proud of my German ancestry. It's you, poor Grits dear, who's barking up the wrong tree."
Any advice on how to deal with these touchy situations would be most welcome.
