Sometimes it's downright scary to talk to a car mechanic. When he starts talking about his ball joint separator, I seriously consider bicycling to work.

The next few seconds of the conversation never made it into your long term memory. The mechanic started to speak in some other language that may not even be used by humans. He did mention something about a planetary gear set…
You: "And the total cost?"
