Good Score

I was meeting a friend at a bar and as I went in, I noticed two pretty girls looking at me.
“Nine.” I heard one whisper as I passed.
Feeling pleased with myself, I swaggered over to my buddy and told him a girl had just rated me as 9 out of 10.
“I don’t want to ruin it for you,” he said, “but when I walked in they were speaking German.”
