And from my family... (haven't seen anyone else come up with some of these, wonder where WE got them)

While looking through a knothole in father's wooden leg
Why did they build the shore so near the ocean
Well, a snake's belt slips because he has no hips
And his waistline is just below his necktie

(Two beginning lines)
Go get the axe there's a hair on baby's chest
And a boy's best friend is his mother

(two more beginning lines)
Go get the Listerine; sister has a beau
And we hope that Grandma's teeth will soon fit Jenny
