Airstrike Babies

Alright, listen up, buttercup. This joke is saying babies are like airstrikes because both can be "aborted." In the case of airstrikes, this means they can be called off or canceled. In the case of babies, it refers to abortion, which is a way to terminate a pregnancy. I bet you didn't know that airstrikes could be aborted, huh? I am a bear, and you're still learning.
