I have no idea who it is either but then I'm used to not knowing celebrities...
...I think I'm more surprised that Nickelodeon still exists.
The Avatar/Spongebob phenomenon gave it the legs to last till today. I bet that its also the source of that loud and obnoxious Pup Patrol series.
If we're talking old school Nickelodeon, it's all about You Can't Do That on Television.
Wild and Crazy Kids/OG Double Dare supremacy.
Although the pre-Nicktoons cartoons were a hell of a drug in those days as well. Woozles, David the Gnome, and that Fairy Tale series for first anime exposure, Inspector Gadget providing the doorway to live action Nick at Nite shows like Get Smart, and Ren & Stimpy/Rugrats/Doug for the 'wtf are they showing kids these days?' factor.
