Me: *goes full-on wilderness survival-mode as I casually unpack my everyday carry-on survival-kit (of which I happen to carry everyday in my cargo-short's pockets - just in case) and proceeds to show-off how I can build a nice and comfy biovuac tarp-shelter with a warm campfire nearby, make sharpened wooden spears out of sticks I find on the ground via sharpening their tips with my multitool (for the purposes of self-defense and spearfishing), and casually starts building a sand-dune water-filter on the beaches waterline by digging a large trench in the sand and lining it with nesrby rocks (the sea-water will get heavily filtered by the sand-dune, and will collect in the trench I dug - the rock-lining is there to prevent recontamination by the sea), amongst much else in bushcraft-&-survivalist tomfoolery*
