After a little research on why Martin Short is part of the “5 Timers Club”, even though he has hosted the show 3 times, the reason Martin is a part of the club ’cause he was a regular cast member from 1984 – 1985. The year 1985 has the number 5, therefor, that’s what makes him qualified for the, “5 Timers Club”. Anything that has to do with 5, makes an SNL star eligible. I thought this was interesting, so I thought I would share it. Now I understand why he was a part of that group shot photo.
Edit to add: Same thing with Dan Aykroyd, he hasn’t hosted SNL that much, he was regular cast member from 1975-1979.
