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...
Unfortunately, the mammoths weren't killed by the radiation and became the Ancient Mutant Not-trained-in-martial-arts Mammoths™ or the AMNoM™ for short.
Fortunately, all the mammoths sought was the sensei. I volunteer to bear that burden. The first lesson is taking place at my humble dojo as I'm writing this.
Fortunately, that cheese is now gone and they have a new enemy: the NINJA CHEESE! They swear to protect humanity and annihilate all abominations that threaten us from now on.
Unfortunately, mammoths’ desire for revenge fueled them with enough dark magic that it constructed joints, sinews and muscles holding them fast together. All black like tar but the blackest are their hearts. Now nothing can stop their murderous design!
