It was a dirty day at the park for Jack Black, wife Tanya Haden Black, and 2-year-old son Samuel Jason on Tuesday. The family (minus 3-month-old Thomas David) explored the woods and stream area and got a little muddy — look at Sammy’s face, Tanya’s hip and Jack’s leg!

Jack latest film, Tropic Thunder, is in theaters now, while Tanya and her family are currently promoting Charlie Haden Family & Friends’ Rambling Boy, the latest studio album from her father, out next month. Along with triplet sisters Tanya, Petra, and Rachel, brother Josh and husband Jack also appear on the disc!
