You are right, Sternvogel. I stand corrected. :o
- William McKinley.
I wasn’t sure either, which is why I used the question mark.
Yeah, and if you combine the two you get what Jim Croce called the “interrobang.” 
It’s strange that there have been so few replies…

The platypus is a monotreme , or of the order Monotremata, which also includes the echidna (spiny anteater).

As I recall, it was Reverend Dimmesdale.

It’s a method of laying bricks or stones.
And, of course, the skin on a cat’s nose is the leather.

I was thinking of Lev Davidovich Landau, who was riding in a car in 1962 when it collided with an oncoming truck. He suffered, among other things, a fractured skull and brain hemorrhaging and laceration. He was made deaf, mute, blind, and paralyzed; he made a partial recovery but died in 1968. 
- What jazz combo recorded “Twisted” in the late 1940s?
By Wardell Gray (who also wrote it) and it appeared on his album titled Central Avenue on the Prestige Label. It was recorded on November 11, 1949.
It was Lefty Gomez, all right, but he beat the Cubs in 1932! :o
(This was the year before Cuban Dolf Luque, pitching for the Giants, beat the Senators in the last game of the 1933 Series.)
