Ok for example, I start by saying,"Unfortunately there was a giant evil pillow on the the loose; then the next person would say...Fortunately I had a knife with me and stabbed a hole in it"
Ok lets start. Unfortunately I was being chased by an elephant...
Fortunately, we can get rich by stealing the richest bank in the world... and that bank is right there *points to a place that is so far we can't even see it*
Fortunately, we can just enter the bank as everyone else, steal the weapons, use the weapons to steal the money and use the money to bribe them, then, we attack the bank again with the weapons and steal the money we've bribed them!
