Ron Howard

It's been 43 years since he left Mayberry, but Ron Howard still has a little bit of Opie in him when it comes to milking cows.

Howard spent some time with his significant udder last weekend at a farm in Upstate New York -- tugging on a cow's undercarriage while hanging with his family -- and TMZ has the milky pictures.

Ron and co. stopped by Philipsburg Manor in Sleepy Hollow, NY on Saturday -- proving the age old adage ... you can milk just about anything with nipples.
