Your genes are incompatible with those jeans.
I usually pop into a coffee shop in the morning to enjoy a cup of coffee with my daily dose of reading material. Today an elderly couple sat down at the table next to me, and I could help but giggle a little eavesdropping on their conversation. It went something like this:
(she picks up his newspaper)
- Him: There is an article in there about fat people.
Her: What about them?
Him: They think that the reason they're fat is because of their genes.
- Her: What, they get fat enough so their jeans will fit?
Him: No their genes.
Her: What about them?
Him: Genes like DNA.
Her: I don't know anything about those fancy jeans. People spend too much money on those.
