Sir Elton John doesn't mind getting his hands dirty ... or wet!

The new daddy, along with hubby David Furnish and son Zachary, got up close and personal with a dolphin at the Georgia Aquarium in Atlanta.

Elton, 64, has no problem bending over to pet his finned friend. Too bad he and David appear to be having way more fun than little Zach.

What a hands-on dad!
