What's My Line with guest one of the guys who played Bozo the Clown (not Larry Harmon) (1969)

I posted the first half of this here before but now game show YouTuber AdamNedeff has posted the second half and it's interesting. It features the guy who just appeared as Bozo the Clown without his make-up. Not sure if this is the only episode of What's My Line in which the exact same guest appeared as the challenger in two consecutive installments.
