A male character learns that his wife is expecting a baby. Does she actually inform him of this? Not necessary. She just sits there looking smug and knitting something (often a very small sock), and he gets the message. Often used in works made before it was considered okay to discuss the subject of pregnancy, as it has the benefit of also informing the audience that the woman is with child, without having to actually say it.

- Lampshaded and Subverted in I Love Lucy. Lucy and Ethel think their husbands are going to join the army and take up knitting. The husbands notice them doing this, and naturally assume they are both having babies.
