When Jack was told to “go fuck himself” by his now ex-girlfriend, he didn’t think it meant that it meant his dick would fall off and transform into a dildo.
Jack and his friend were on a road trip, and unbeknownst to them, the Great Shift was only a minute away. The Shift only had about a 1 in 10 chance of affecting people, so they wouldn’t have had much reason to worry either way. Luckily for Jack’s friend, Ari, he hadn’t been affected by the shift. Jack, however, was not so lucky.
