I just started watching the reboot/revival and am only now realizing the significance of some of the character names:

• John, the baby, likely named to honor John Mahoney
  • They named the bar after Mahoney as well.
• Moose, the firefighter, named after the dog that played Eddie
• David Crane is obviously named after DHP

I'm only on the 4th episode, so there may be more I missed or haven't noticed yet.
