Al Capp scripted a number of spankings in
Li'l Abner that we've seen over on the main site (and he may have done even more in the strip's later period - I was forced to stop buying the reprint collections years ago because I couldn't afford them any more). His spankings were generally meant to be humorous, but he also had many characters "getting the boot" one way or the other (The Kigmies were a race that loved to be kicked where they sat down) and I have to believe Capp took greater delight in such scenes than he did in spankings.
Phil Sweetspot 
has found two boot-to-the-behind scenes of interest to us, one featuring the lazy
Moonbeam McSwine and the second with
Daisy Mae Scragg. Let's take a look at them now as part of
Li'l Abnerpalooza. (Scans by Phil S.; minor edits by Web-Ed).
First we have Moonbeam McSwine being auctioned off in Ragbagdad while a despairing Daisy Mae is left behind:

The slave dealer sends Moonbeam off with a good swift kick. Capp might get in trouble if he were alive in today's PC world, but in 1951 it was still o.k. to use for a story idea the existence of slavery in even the modern Muslim world. Notice also Capp's use of irony as the slave dealer refers to the buyer's "love [that] surpasseth all understanding" when he offers to throw his aged father into bondage as part of the deal.
Seven years later, Daisy Mae receives a good kick from Mammy Yokum - except it isn't part of the strip's continuity!

Interestingly, Capp drew the booted beauty's booty merely to capture the reader's attention! Was this an unintentional confession that someone giving poor Daisy a swift kick was what he himself most wanted to see? Or was it simply that he thought the readers would enjoy giving a beautiful girl a kick, never knowing that surely a greater number would have enjoyed taking her over their knees? Capp was a talented man, but not always a very nice one,
Of course we'd rather see a spanking, but Daisy Mae is so nicely bent over here (as a result of the kick rather than a prelude to it, we'd say) that I couldn't resist cutting Mammy out of the drawing and rotating it so that it looked as if perhaps Daisy has just received a tremendous swat with a paddle after bending well over

!
As a matter of fact, next week we're going to see Daisy Mae drawn in a position very much like this one, panties down and bottom bared, and colored by
Doctor Cylon!
