Almost every branch of every story in Choose Your Own Adventure books ended with bold, centered text that said:

     THE END

But there was one story I vaguely recall where if you made the "wrong" choice, you fell into a bottomless pit (the books were always in the second person) and you kept falling and falling, forever, and the text said:

    THERE IS NO END

I still remember the chills I got reading this. I wonder how kids these days get their introduction to existential horror?

Much more horrifying: you are (rather unexpectedly) bewitched into eternally picking up pieces of a broken china cat!
