The general rule that you should always bring a towel just in case you do something stupid so at least people will say "Hey that guy/gal really knows where their towel is". Coincidentally this is also the meaning of life and all questions because all answers can be deprived from 42 an example of this would be: How many minutes dose it take to make a marshmallow peep answer 42 because 4+2=6 and it takes 6 minuets to make. Part of the 100+ general rules of the universe.
Bob: What should I bring to my camping trip to Death Vally?

Jim: Always remember Rule 42: Always bring a towel.

Bob: Why? a towel there is no reason I would need it.

Jim: But what if you get lost then with a knife and a little time you can make a turban like hat to shield your eyes so you don't over heat and go temporally blind, or what happens when you need some sort of bag but you only have a knife a towel and some rope you could make your own knapsack.

Bob: Thanks Jim for reminding me about Rule 42.

Jim: No problem.

If it exist, there is a pony version of it. No exceptions.

Started by the brony fanbase of My Little Pony: Friendship is Magic.
There is nothing wrong with non-ponified things, ponifying just makes them around 20% cooler.

Guy 2: Rule 42

The original Rule 42 was stated over 9000 years ago, at the end of World War I. It states, "The face is not important compared to this." The modern definition can be considered Tits or GTFO
"Oh, hai guys! I'm new to this thread lolz. What's up?"

"Rule 42 bitch!"
