I always wanted a mini fridge in my room so that I could be lazy and only stand to go to the bathroom.
Why stop there? You could easily go to the bathroom without standing up as well!
Step 1: Find a long plastic tube. This needs to be approximately 4-5 feet in length and flexible. A good way to get one is by cutting off the hose of a CamelBack, and taking off the aesthetic cloth part of it.
Step 2: Grab a couple of empty 2-liter bottles.
Step 3: Attach one end of the straw to the bottle, and the other end to your penis. Now you never have to stand to go to the bathroom again.
Step 4 (Ladies only): Instead of attaching it to your penis, you're going to need to get a small funnel. This will be uncomfortable, I'm sorry.
Disclaimer: I am not responsible for any injuries sustained by getting aroused while wearing the tube. If fail to secure your tubes correctly, leakage is also a possibility.
I have a few ideas on how to avoid standing if you need to take a shit as well. Be sure to comment if you're interested.
