One throwaway line from Red on "That '90s Show" actually references one of Kelso's dumber mistakes on "That '70s Show."

Red brings up one incident in particular, reminding Kitty and revealing to Jay, "Michael Kelso glued himself to our refrigerator," in a callback to a season seven episode where Kelso manages to do just that.
