Insert your own pun here

Alrighty, here's one that's directly related to both religion and demographics. You've all seen by now the news item about the men in Serbia trying an electrifying new form of birth control: electricity.

Men in Serbia are lining up to have electric shocks delivered to their testicles as part of a new contraceptive treatment.

Serbian fertility expert Dr Sava Bojovic, who runs one of the clinics offering the service, said the small electric shock makes men temporarily infertile by stunning their sperm into a state of immobility.

He said: "We attach electrodes to either side of the testicles and send low electricity currents flowing through them.

"This stuns the sperm, effectively putting them to sleep for up to 10 days, which means couples can have sex without fear of getting pregnant.

"The method does not kill the sperm permanently and it does not affect the patient's health."

Dr Bojovic added patients were now lining up at his fertility clinic in Novi Banovci for the shock treatment, as it had none of the problems attached to using condoms, the male pill or having a vasectomy.

He added: "We are hoping to have a small battery powered version on sale in the shops in time for Xmas."

I thought I couldn't laugh any harder, but Bob the Ape has a little advertising jingle that had me rolling on the floor with tears rolling down my cheeks.

If thinking of paternity is frightening,
But contemplating continence inflames you with a rash,
Then come to us, who've tamed and harnessed lightning,
And we will solve your problem with a crackle and a flash.

No unexpected offspring will entrap you
And terminate your lecherous adventures with a crash;
Just drop your pants and we will gladly zap you -
Then find yourself a willing girl and mount her with panache!

With your spermatozoa knocked unconscious
You will not need your prophylactics - throw them in the trash!
Enjoy a sex life active and rambunctious!
