The theory is that if someone names the 7 dwarves they will say "bashfull" last.............or if they can't think of that "last" dwarf more then likely it will be bashfull..............I didn't tell it well
Countless times I have done this at small parties and gatherings and most of the time I drop jaws:
I secretly but in full view of everyone write down the name "Bashfull" on a large piece of paper...then ask someone(or a couple) to name the 7 dwarves. When they have named the first 6 and are struggling to remember the 7th I hold up the card
Yes, I do look a little silly when they do remember Bashfull.....but so far, that only happens a fraction of the time.
