In the spirit of Chris Anderson’s E-mail Charter, I offer the 20 possible responses of a Magic 8-ball:

• It is certain
• It is decidedly so
• Without a doubt
• Yes – definitely
• You may rely on it
• As I see it, yes
• Most likely
• Outlook good
• Signs point to yes
• Yes
• Reply hazy, try again
• Ask again later
• Better not tell you now
• Cannot predict now
• Concentrate and ask again
• Don’t count on it
• My reply is no
• My sources say no
• Outlook not so good
• Very doubtful

Without going so far as to suggest they should be chosen from at random, I would very much like to have an e-mail client that included each of them as a one-click response button in a toolbar.  And yes, OK,  you might throw in a “Random!” button just for fun.
