A Swinging Bad Time

You’ll have to forgive me for not replying to your email.
You see, I’ve got one of those laptops with a fingerprint reader.
The problem is, I cut my finger in the kitchen while chopping up lettuce for salad.
Now the laptop doesn’t know who I am.
There’s an option to use the password, but it’s been so long since I’ve used a password for my laptop, I can’t remember my password.
So I went to a hypnotist, and he swung a watch in front of my eyes for an hour.
But all I could recall was “A swinging watch.”
