It's unusual to see Jack Black so out of his element (in terms of performances and wacky antics), but we're happy here at Splash to see him hanging out with the kids on Labor Day. This fun dad was spotted at Coldwater Park in Beverly Hills playing with his son Sammy, who looked like he wanted to race around all day long. Son Tommy followed close behind in his stroller with Jack's wife Tanya Haden.

Awwwww. I wasn't expecting family cuteness from him this morning!
