Back when I was in college we did one of those stupid "team building" exercises where the someone asked a question a bunch of questions and we'd all respond and share our answers. One of the questions was "What famous person would you most like to have dinner with and why?" When my turn came up I said "Gandhi" and everyone nodded their head approvingly. Then I quickly followed up with "...because I'd probably have more to eat if it was just him and me."
Only a couple of people laughed. Everyone else thought it was a tasteless joke. Some people just don't have a sense of humor I suppose.
