\(\displaystyle Here's\ a\ weird\ proof\ I\ heard\ once...\)
\(\displaystyle 'I\ think,\ therefore\ I\ am\'\\)
\(\displaystyle Forgive\ me\ for\ still\ existing\ if\ I\ choose\ to\ stop\ thinking\ for\ a\ while.\)
\(\displaystyle Here's\ another....\)
\(\displaystyle 'We\ experience\ what\ we\ believe,\ unless\ we\ don't\ believe\ that\ we\ experience\ what\ we\ believe,\)
\(\displaystyle in\ which\ case\ we\ don't,\ which\ means\ we\ do\ experience\ what\ we\ believe.\ '\)
\(\displaystyle Notice\ how\ '\ in\ which\ case\ we\ don't\ '\ assumes\ the\ statement\ is\ true.\)
