Favorite self-imposed challenges?

an oft-recycled and harsh self-imposed challenge:

4. Master of Kefka's Domain:

i walk aimlessly around Kefka's Tower without: engaging in close combat, pulling any switches, traveling through any tubes, and certainly flushing any toilets.

should i succeed, the timer will be at 99:59, and i'll be as blue as this website's default background.

nothing will have been accomplished, aside from maximum frustration in myself and annoyance in everyone near me.

Lmao, sounds like what happens when I let my child play, though admittedly she really likes flushing the toilet (and trapping NPCs in corners while eating at their tables).
