My dad is a private pilot and sometimes we take relatively long trips in a small little Cessna. By long, I mean ~5 hours, and by small little cessna, I mean it doesn't have any bathrooms. How can you take a 5 hour trip without a bathroom? Why, you purchase an HRE- Human Range Extender, like this one, the Little John*:
A brightly colored, portable urinal.
Now, this may seem a little bit unfair. Obviously it is far easier for a man to essentially pee in a bottle than it is for a woman to do the same. Thankfully, the bathroom engineers responsible for this product spent some time tackling this entrenched inequity and developed the Lady J adapter:
They go together like this:
Someone once told me that every great journey begins with a trip to the bathroom. Gender equality will prevail.
*Note: Apparently a competitor to the Little John was marketed under the name "The Wall Street Urinal"
