The pranks between John Stamos and Nick Jonas have reached extreme levels. Stamos posted a picture on Instagram showing him getting a tattoo of Nick’s face on his forearm. Stamos captioned the pic, “#jobrosforlife.” Nick commented, “Okay, okay.” The back and forth between the two began when Stamos wore a Jonas Brothers t-shirt at October’s American Music Awards. Jonas countered by posting a pic of himself wearing a Stamos shirt. It has continued to the point of ink…we think.
