Yes, but then the general contract provisions stuff gets to be longer than the disclaimer part and it's not cute any more.
I mostly did this because my attorney is a frequent party guest and one of those people who hoards his sauce until the next season. He got a good laugh at it but pointed out that I had left out a bunch of important stuff, which if I could just find a way to send sauce to his in-laws in England he would be happy to take care of for me...
