Matt's flirting has a very high rate of success, so he thinks that he is really good at it. Foggy tries to explain that he's not good at flirting, like at all, but it doesn't matter because people would sleep with him no matter what he said.

Just Foggy being so, so perplexed when Matt uses terrible pick-up lines with high rates of success. Bonus for Foggy showing Matt how it's really done. By demonstrating. On Matt.
