Three pregnant women were happily knitting in a doctors waiting room. After awhile one of them puts down her wool and swallowed a pill, "I take iron so my baby wont be anaemic." She said.
The next mum to be stopped knitting and then popped a tablet of her own, "I take calcium so my baby will have strong bones."
A few minutes later, the third expectant mother laid down her needles and emptied half a bottle of pills down her throat. "I take thalidomide," she says, "I don't know how to knit sleeves!"
