During a show with the Beach Boys in New York, Full House alum John Stamos was strumming away on the guitar when he got the feeling something was a touch awry. Turns out?the musician had accidentally split his pants on stage. Stamos took it in stride taking to Instagram to say, "somewhere towards the end of Fun, Fun, Fun - I felt a slight breeze in the buttocks area....#SplitPants #TheBeachBUNS #showmustgoon."
