He did have a big ego: On the "Battle of the Network Stars" (I believe that was the name of the show) he got mad at Gabe Kaplan for something and challenged Kaplan to any type of contest to settle their differences. Kaplan chose Track, which was fine with Conrad.
Little did Conrad know was that Kaplan was a former Track star. Conrad's short little legs didn't stand a chance in the race.
Anyway, I'll miss you, big guy. RIP.
