No. HB was right.

Tombie and his missus have to have a birthday each. Probability of that is 1.

Take Tombie's birfdee as given, whatever it is.

Probability of GoBB having the same birfdee is 1/365.

Same calculation for their better halves.

Probability of both being the same is there 1/365 * 1/365 = 133225 - 1.

But that's just those two in particular.

Probability of *any* two wrathers being in this position - which is really the appropriate calc for this, since all other users have seen Tombie's birthdays and ignored them because their's are different - is much shorter.

But also much harder to calculate.....
