Thanks for posting this! The one about the NY Mets is the first one I remember doing as a kid, and the others from the 60s (Cannon Fodder, War Hawk) brought back memories as well ...
Yeah, brings back some pleasant memories... I too was a regular back in the mid to late 60's. I thumbed through a MAD the other day at the airport - still has some sharp wit and illustrations of present day stuff, Spy vs. Spy and the fold-in at the back. Some things have not changed.
