Funny, I just thought of the one lady who was on both Bullseye and TTD, Wemkea whatsherface that also ended up on Press Your Luck. Can't imagine there were too many folks who got to be on two different B&E shows of the era, especially considering the info shown here.
I think her surname was Sherman.
I don't recall a whole helluva lot, and her appearances were about three years apart anyway.
/as it happens, Dave Wagner was on in 1978 and again in the mid-80s, also a long period in between. So that makes three.
That does bring up something--if you've already been on the show you ostensibly can pass the test again but are they going to take Joker's Wild contestants and "bump them up" to Tic Tac Dough or the other way around? It's not like testing for Wheel of Fortune and being thrown to the wolves on Jeopardy. And Bullseye you could win more than on Joker's Wild and roughly equivalent to Tic Tac. I don't recall anyone who was so egregious where I said aloud "how did this assclown make it through the tryout gauntlet?"
