Well that seemingly came out of nowhere. I believe I heard Mike Sinterniklaas as a henchman and possibly Dana Snyder as Dr. Zin (might have been someone else like James Hong). Mike and/or Dana showing up in a Jonny Quest project is rather amusing to me since they're key voices in Venture Bros., I wonder if Doc Hammer and Jason Publik will pop up somewhere. I'm pretty sure I heard Jess
HarnellJess Harnell voiced Wakko, not Yakko. Yakko was voiced by Rob Paulsen.
WHAT, is Yakko Warner in this, saying "Hello Nurse"?
