I'd like to think that the comic-marring-mathematician who marked up my copy of WOODY WOODPECKER # 124 (Gold Key Comics, Cover Date: July, 1972) at least cried out "A SCRATCH-PAD! A SCRATCH-PAD! MY KINGDOM FOR A SCRATCH-PAD!" before taking the drastic step of corrupting my copy with his cursedly copious calculations!
Then again, if "Don didn't doodle as he did", I wouldn't have gotten this book for a quarter!
You know... "A Quarter!" The price of a "Drooler's Delight" - my favorite Woody Woodpecker cartoon!
So, here's to Don (whoever and wherever you are), hoping your math came out right, and you didn't forget to, like "carry the four", or sumpthin'!
