What's more scary, you pick a situation (thread for Halloween)

Investing all your money in a 401K in stocks that can't be sold until the end of the day, or trusting a dancer with something valuable? Two or three times when I had my first brand new car, I had a dancer ask to drive it and finally let each one drive it for a minute or two. That made me about as nervous as putting all my money into stocks. I did have them show me their drivers license first but I wasn't sure if the insurance would cover everything. I thought it would and I knew where they lived.
