A very old-school pun for today. Indeed, it was so retro that I carefully combed through a summary of my previous gags to make sure I had not made this pun already. As you can see, there was no prior use of this version of the pun.
Some days I long for the rich vein of humour I found with the series of barbarian puns. Maybe similar inspiration will strike again.
