Have you also noticed people saying “once and a while” a lot lately? I always thought the phrase was “once in awhile,” meaning that within a long period of time, something only happened once.
There is a (very nice) song by the band The Killers, and about halfway through the song, the singer says, “every once and a little while” very dramatically. It has always bothered me. I listened to it ten times just now to verify and he very clearly says it. What I find really interesting is that I also did a search for the lyrics on a bunch of those lyrics websites and every single one of them corrected it and used “in” instead of “and”. Apparently, lyrics enthusiasts are also fans of grammar!
