We've all been there, your mate who is brain dead when it comes to cars says something that makes you want to pull your hair out.
It always seems to happen at the worst possible times, when you're with people who are car literate and they say something that embarasses the both of you or they just make an ass of themselves so much that some of it rubs off on you and you can't help but feel embarassed to be near them at the time.
One of the worst I've ever heard is when I heard someone say "Plymouth stole Hemi Orange from Dodge", granted some people might not know that Chrysler owned both Dodge and Plymouth at the time but come on they even used the same engines in most of their cars so is it not common sense to know that they're both part of something together.
Let's hear the worst things you've ever heard.
PS: Sorry if there is a thread for this already, it seemed like a topic that may have already been created but I searched and couldn't find one.
