"Was hard to hear of his passing... First met George Wendt on the set of Cheers... One of the warmest, funniest guys I've ever come across... Welcoming as the star he was, incredibly giving as an actor in rehearsal (and when the cameras were rolling)... ," Kramer, who guest starred on an episode of "Cheers," said on Instagram. "Also the first one to make sure I had a beer in my hand at the end of the night... We shared a history of work with the Calgary Stampeders and exchanged many stories over the week... Cheers, indeed... Many thanks for the laughs and the education... RIP."
