I used to keep pet spiders, but they became high maintenance and kept dying. Plus, they were smaller than thumbtacks where I lived (US NE), so it wasn't a big deal. Then I moved to US SE and realized how big these itsy-bitsy beings could be.
My longest time to, I'm just going to say, hold it in. But, I don't think I recommend it, but I was curious. (told you it's sounds crazy, but should of mentioned, not a good idea)
Ya know, (ok you were wondering so I'll tell you) pee. My record? Good question, I'm trying to get past 3 hours without going to the toilet like I did last time (told you it's probably not a good idea) That personal challenge was brought up in my head. One time, we was stuck in a traffic jam that lasted for 3 hours. Now, the memory popped out of nowhere and that's why I'm doing this. (and yeah it's uncomfortable)
