Hello!
Your task is quite interesting, simple and also challenging.
Here are my samples:
I CHALLENGE YOU TO run in high heels over the frozen pond.
I CHALLENGE YOU TO plant the Venus flytrap in the middle of the office, where no plant is allowed, for no particular reason.
I CHALLENGE YOU TO hide in the city center. You have to escape, hide in 5 minutes, because unknown people are following you for no reason at all.
I CHALLENGE YOU TO write a poem about freedom in five minutes and read it in front of the parliament, with a loudspeaker in your hands.
I CHALLENGE YOU TO write an e/mail why you were fired overnight without explanation and send it to the most known politics in town.
I CHALLENGE YOU TO try out the robot that is designed to massage women's breasts.
I CHALLENGE YOU TO explain the kid in the store that you cannot buy him a toy and than make him stop screaming. He said he is your nephew. That is not true.
I CHALLENGE YOU TO try just recently cooked snail.
I CHALLENGE YOU TO put on the new Armani coat. Tell the journalist in front of the camera why the coat is so much better than the last one you bought, if it had no globally known label.
I CHALLENGE YOU TO stop the first celeb that goes by on some popular event and ask her why was she stalking your friend, the journalist, in front of his house.
I hope you like my ideas, I can come up with some even more interesting.
I hope you will pick me, because I really like to search for new ideas!
Wish you a nice day!
