I pointed this out in another blog's comment section three weeks ago, but by golly, the Ol Man's said it again

okay, so it wasn’t with corn pop — maybe Neil Kinnock?

No, Biden did not drive an 18-wheeler, not even with Corn Pop riding shotgun. He made the same claim last month, expanding from his driving a school bus one summer to “driving semis”. I took the trouble to look up Maryland’s commercial license system and, at least as of this year, there are three types, ranging from the easiest to get: school buses; to the hardest: 18-wheelers. Requirements were probably looser in 1910, when Joe was on the roads, but I earned a Class 1 commercial license (the big rig one) in 1974, and even then, there was a substantial difference in requirements.

The line about “Popping little white pills” in “6 Days on the Road” would be apt here, but in view of Joe’s age, maybe this one, instead.
