Sans undertale:
"Do you wanna have a bad time?"
"Do you wish to have an unfortunate experience?"
"I ask if you are capable to engage in a terrible experience including yourself, and I being the cause"
"I SANS THE
SKELETON WISH TO ASK IF YOU CAN COMPREHEND THE FACT THAT I
WILL GIVE YOU AN UNFORTUNATE TIME DUE TO THE FACT THAT YOU ENDED THE LIVES OF WHO I CARED FOR."
