Matt LeBlanc has posted a goodbye to his friend on stage and off, Matthew Perry. On “Friends” they were roommates and best friends. On stage they were a great comic duo, often left to their own devices in the show while Rachel and Ross were taking up time, or Monica and Phoebe were involved in Lucy and Ethel type antics. LeBlanc’s message is tearful, with a funny, sarcastic ending — just like Perry would have done.
