"Happy Family" by Barney and Freinds. Shamelessly ripped off from "This Old Man", Traditional. Tab By Will Betts.

Standard Tuning (EGBDAE). No Capo Necessary.

Here is the melody. My version is in the key of F. I think you'll be able to work out the rhythm on your own.

I also worked out an emotional ballad version of this song, which is always good for a few laughs. Play it slowly and exagerrated and strum the chords as slow downstrokes.
