John Stamos is 50. Have mercy! Uncle Jesse is getting old.
The actor celebrated his half-century birthday Monday with his "Full House" castmates, who have kept in touch since their sitcom went off the air in 1995.
His on-screen wife Lori Loughlin and TV family posted all the details on Instagram for fan-viewing pleasure too.
"@bobsaget was the perfect emcee last night. Hysterically funny as always!" Loughlin wrote about costar and Tanner family patriarch Bob Saget.
