That is the title and has been for some time of the jokes section of Reader’s Digest.
It comes from the Bible verse that says a merry heart doeth good like a medicine.
It’s been a long day that began at 7:00 AM and lasted until 10:30 PM.
But I’m feeling great. I have done nothing but laugh all day long.
Nothing like laughing with good friends to make one feel better.
