...but it's a dry heat! 

I wish!
Right now it's 106 feels like 122 -- that's due to humidity, not dryness.
Of course, there's a good joke about "the dry heat":
"So is fire".But just saying the effective heat out loud (to a human being, a status which I lay claim to) is crazy.
"A hundred and twenty-two degrees". That's too hot for life.
