there are logic classes that cover the difference between deductive reasoning and inductive reasoning

Star magazine has reported that Britney Spears may be having twins, based on evidence that 1) she is fat, and 2) she's been shopping in both the girls' and boys' departments.

First of all, this is the very same magazine that routinely publishes photos of Britney eating Doritos and guzzling Red Bull. Women get fat when they do that. Women get fat even when they don't. Pregnant celebrities ("baby bump," how cute) aren't exactly the model of what the human body was meant to do.

Second of all, if you were fantastically wealthy, you could buy as many baby clothes as you want and then get rid of all the ones that don't properly coordinate with your baby's gender.
