Did I hear correctly in the second video? They both has a goldfish named “George”? No one else finds that worth remarking on? Surely P(both have goldfish named George) << P(She will guess his pet’s name|their pets have the same name). So why are we focusing on the latter?
More relevantly, P(both have a goldfish named George) << P(they don’t, and there’s some trickery going on)
It’s actually quite a useful clue—obviously no psychological “mind-reading” technique could force it, so it must be some other trick, most likely the one garethrees suggests.
