My mother used to say, "Don't make a canary.", which was her mispronouncing of the Yiddish "Keinohera", tempting the evil eye.
That is why, whenevre a Jew says something complimentary, he must temper it with a disclaimer or, at least, by spitting three times.
For instance, he might say, "What a beautiful baby, keinihera." That evil eye is always on the lookout for good looking children.
My ex stumbled into a wonderful spoonerism, some years ago. We were driving past the Wonder Bread bakery, in Conshehocken. She took a deep breath, smiled, and said, "Oh, I love to smell the bed breaking." Hell, who doesn't?
