LMAO!! That is good! I feel like calling a dealer now: Hello? yes. I just drove over 30,000 miles, and not a single spark plug blew out. Can I make an appointment to have this checked? I don't need to tell them I have a 300.
I've seen a few trucks with the Calvin character taking a leak on a sticker the shape of a lemon with the Ford logo, or on the factory logo.

 

whoops..this post was supposed to be a response for flying sparkplugs. Sorry for the confusion
