As we discussed previously, Dial M For Monkey was one of the backup features on Dexter's Laboratory. As you can see in the intro, Dexter never believed that his pet would amount to anything, and so the science-obsessed youth gave up experimenting on Monkey, unaware that the simian was in fact endowed with super powers after all.
To be honest with you, I wish I had pulled this up earlier this year, after wrestler "Macho Man" Randy Savage had passed away. Under contract to WCW (a sister company to Cartoon Network and its sister channels at the time), Savage began dabbling in cartoons, and this would be his toon debut, guest-starring as "Rasslor", a send-up of the Fantastic Four's cosmic foe, Galactus. The Justice Friends guest in this episode as well.

Note how Savage was given a little Dr. Seuss in his dialogue. "Macho Man" would later become a recurring guest on Space Ghost Coast-To-Coast, but that would be the extent of his work for CN. The man sold a ton of Slim Jims back in the day, as well as wrestling tickets. Somewhere up there, he's giving a clinic in Heaven.
