"To the Moon, Alice!" That was actually just a hilarious joke about spousal abuse from the classic TV show, The Honeymooners. He meant it as "[I'm going to knock you] to the moon" and not "[I love you] to the moon [and back]", but DETAILS, right?
Chances are, you're not constantly threatening to punch your spouse in the face. Chances are you want to let them know how much you love them this Valentine's Day. Try this Moon and Back Print ($22, Gus & Lula). It's sacchrine and sentimental. The stuff Valentine's Day is made of.
