Seth Rogen and other 'Superbad' fans celebrate McLovin's 40th birthday

Ready to feel old? Superbad scene-stealer McLovin — played by Christopher Mintz-Plasse in the 2007 comedy favorite — has officially hit the big 4-0. And the character's creator, Seth Rogen, celebrated that momentous birthday with the ultimate gift: a viral tweet. "Happy 40th birthday McLovin," the actor and screenwriter wrote on Twitter alongside a picture of the character's June 3, 1981 birthdate. The 39-year-old Rogen also made sure to boast of his own relative youth. "We wrote this joke when we were 14 years old," he added, the age he and longtime collaborator Evan Goldberg were when they first starting penning the script that became Superbad.
