Blowing a Gasket

I guess I never really, truly understood the meaning of the phrase "blowing a gasket" until I spent my entire day laying irrigation pipe. I always figured the idiom aptly described the look my mom gets when my brothers and I do something uber dumb... but as I previously mentioned, after today's debacle, I do concur that a leaky irrigation pipe provides a suitable metaphor for an angry ranch mom. (Or an angry grizzly bear, but I digress.)
