My favorite of those was “Don’t Blow Your Top”

See it was a bust of a dude wearing a Top Hat. Only the dude’s head was a party balloon…and there was some card board face or something. The top hat was put on the balloon head…but the top of the top hat was a seperate dish like piece that was held in place only by friction…and there were pins on the bottom. And you’d add marbles to the top hat until it was too heavy for the friction and would slight down and BANG!

Who knows what the rules were, we just liked making the balloon go bang. I think it got taken away when we realize we could just skip the whole hat and marble thing and just pop the balloons with the pins…
