During their trip, his friend Johnny played a funny prank on Patrick while he was sleeping and gave him a star flash tattoo.

“Stupid @Johnny_L0we put this flash tattoo on me while I was sleeping and now it won’t come off,” he tweeted along with a pic of himself.

FYI: Flash tattoos are metallic jewelry-inspired temporary tattoos.
