In Sickness And In Health Puns

The head veterinarian at a zoo noticed something alarming in a patient’s record. A monkey that had been a healthy weight at its last checkup was now recorded as being only half that.

Fearing for the monkey’s health, he went and saw it, expecting it to be sickly and skeletal. However, the monkey seemed totally normal. Confused told his staff to weigh the monkey again.

They did, but the number they reported was still astonishingly low. Sure it was a mistake, he went to weigh the monkey for himself. But when he put the monkey on the scale, it showed a number that was still far too low, and couldn’t possibly be right.

After a moment he spotted the problem: behind the scale was a grab bar on the wall, and the monkey had stealthily grabbed it with its tail, and was supporting some of its weight off the scale that way.

So the monkey's weight was fine, they just weren't paying attention to de tail.

Newscaster: ...and in health news, a study showed that frequent orgasms help support immunity....

Mom: Honey, that must be why you’re never sick (winks)

Dad: Yeah, that’s because I’m self-medicated!

Growing up in Sydney there was a 'Baby Health Centre' across the street. My dad was an older guy so had the typical 'old man pun' sense of humour. Around Christmas one year I was walking by with my dad and he goes 'Hey. Where do baby elves go when they're sick? To the baby ELF centre!' Face palm.
