"The Moon Is A Lie" Carry-All Pouch
The best way to make an instant connection with someone is bonding over your shared belief in a massive conspiracy. Since we don't have any "who really killed JFK" backpacks, this fake moon landing carry-all pouch will have to do. You'll talk with your new buddies for hours about how the flag shouldn't be able to blow in the wind and how the lunar module should have left a crater upon impact. If that doesn't get them immediately hooked, point out that there's clearly a moon in the sky ... above the moon depicted in the scene. You'll have made a friend for life. Though you'll never know their real name, because you cannot be trusted.
