Notes:

J.K. Simmons voice acted for both of these characters. Originally, I posted a similar picture to Imgur that said something about "Cave Johnson being a secret furry" as a joke, but apparently it was too offensive and was down voted several times for making that joke. I changed it to this and posted it here because it made more sense and was more relatable to the portal universe. If you want to see the version I posed to Imgur, go here > http://imgur.com/8RAOOdp
