How to impress a boss

Last night was the first time for a new babysitter. She will be coming back for several reasons, but there is one for which I want her back. No, it has nothing to do with her looks. I want her back for more babysitting jobs because she found me incredibly funny. This wasn't the "I'm laughing out of pity for your pathetic attempt at humor". She was guffawing! Debbie had to even ask what I said that was so incredibly funny. Just a note for future baby sitters (and any other possible employees), find me funny and you are a shoo-in.
