I never heard or thought of most of these, although “Round John Virgin” from “Silent Night” was used as the name of a character in the mondegreen-fiiled animated special “Olive the Other Reindeer”, and MilliCal and I use “Later on we’ll perspire” from “Winter Wonderland” as an inside joke.
Many of these mondegreens come from the book Deck the Halls with Buddy Holly. However, it doesn’t have some of my favorites from that book, such as “Santa baby, Jeff’s disabled under the tree” or “Rudolph the red-nosed reindeer, you’ll go drown in Listerine.”
Yeah, I was saying that their “inside joke” wasn’t exclusively theirs, 'cause I thought it was “perspire” for all these years, as well. Heck, I think I even sang it that way in choir!
When I hear Bon Jovi’s rendition of “I saw Mommy Kissing Santa Claus” I could swear he’s singing “…then I saw mommy tinkle on Santa Claus”(as opposed to tickling). Obviously I know the real words but I think my way is more funner.
The second verse of “It Came Upon the Midnight Clear” has a line that I always thought was “And ever o’er its battle sounds / The blessed angels sing”. Always, that is, until I noticed on the sheet music I have for it that it is “And ever o’er its Babel sounds”.
I’ll admit it’s a Mondegreen, but I still insist that my version makes more sense, darnit.
Go dress ye merry, gentlemen
You’ve nothing on this day
Remember not to save your
Wash for doing Christmas day
And save us all from visions sour
When pants have gone astray
Go find things that cover a groin
Cover a groin
Go find things that cover a groin
(not mine, probably not strictly a mondegreen either)
