A vendor walked down the train corridor selling a type of banana the passengers had never seen before.
Curious, both friends bought one. The first woman peeled hers right away and took a bite—just as the train entered a dark tunnel.

“Don’t eat yours.”
“Why not?” her friend asked.
“Because I took one bite… and I went blind for thirty seconds!”
