Spy vs Spy but I'm back at it again with my nonsense.
Ages ago I loved these two as a kid and especially so when MAD came to CN. I somehow got reminded of them recently and had to draw them- with a twist of course :3c
It took far longer than it should have to search for it on the internet, but I managed to find the Spy vs Spy cameo from Hanna-Barbera's mid-1980's MAD animated special. The entire feature was never realeased to the public, but a small portion of it has been uploaded to youtube.
