Odd Language #131: Colourful Expression

Every so often, I run across an expression that makes it point so well. http://talesfromthevault.com/thunderstruck/comic306.html is a strip of Thunderstruck that has ‘The needle on my kosher-meter just dipped down to “ham sandwich.”

The issue: “kosher” and “ham” do not go together, and the sentence uses this wonderfully. The attitude suits the character making it very well.
