Tom Lehrer
Especially the young ones who never got to hear about Tom Lehrer.
Here is Lehrer’s Lobachevsky.
But don’t take him seriously about Lobachevsky. The guy was a genius.
In any case, what do you think of this quote?
“To copy from another is plagiarism.
To copy from more than one is research.”

You might want to change the photo: pictured is “Weird” Al Yankovic, not Tom Lehrer.
Thanks!
