The cannon’s payload was not, in fact, a T-shirt. It contained the Shroud of Turin—the legendary piece of cloth that the body of Christ was wrapped in after crucifixion. Experts were divided as to whether or not the shroud was real or a fake produced during the Middle Ages, an era when selling “holy” relics was all the rage. That was probably why John had managed to buy it for just $150 off eBay, which he thought was a good price either way (listing: $$$ ACTUAL SHROUD OF TAURINE—STAINED WITH SWEAT OF JESUZ—GOOD CONDITION—FREE SHIPPING—WOW!! $$$).
