Of course you are.
Fortunately, I just came across this article, "11 Trippy Questions." (Does anyone even use the word "trippy" anymore? I didn't think so.)
Even though the authors claim the questions are great for bars, they're also very reminiscent of those thought problems that you spend hours doing in sixth grade. Only to learn the answer is something really obvious -- like zero -- and feel really stupid.
That said, these questions are trippy enough to help you waste at least an hour of valuable work time. Here's an example:
Mary's father has five daughters: 1. Nana, 2. Nene, 3. Nini, 4. Nono. What is the name of the fifth daughter?
Did you choose Nunu? Read the question again. The answer is Mary.
Um, yeah. See what I meant about feeling stupid? Or maybe that's just me.
