Ok, let's see if I can hit the points asked here:
Yes, the hatch is for easy access. No I don't use it.
Boxer-briefs are the bomb.
I had Superman & Boba Fett underroos.
Yes it's nice that the business can be accomplished anywhere in a matter of seconds & it takes longer for the tank to get full.
Side story - A friend, his mother & I were at the movies. My friend & I stopped in the restroom, I decided that I'd embarrass the heck out of the friend. When I stepped up to the urinal, I dropped my pants & underwear to my ankles. Someone walked in & a nonchalantly said "how's it goin'?", the guy kinda nodded & went into a stall. When I walked out my friend (who'd walked out a few seconds before was rolling on the floor. LOL
