Larry Birkhead & Dannielynn Slide Into Some Fun

Larry Birkhead sure looks like he's got the part of Fun Dad down pat! He and his daughter with the late Anna Nicole Smith, three-year-old Dannielynn, enjoyed all the attractions at a farmers market in L.A. on Sunday, including an inflatable slide! Seems Larry is young at heart when it comes to spending time with his tot!

Any time we see Larry and his adorable daughter together, they always look like they're perfectly happy!
