SO, THESE ARE WHAT THEY CALL THE “DOG DAYS OF SUMMER.” Never having ever been a dog I cannot personally vouch for much beyond that statement. Unlike dogs, I can and do sweat, but instead of “like a dog” I sweat like a pig. Not pretty.
At least, that is the phrase – “He sweats like a pig.” I have to take that as truth because I have not managed to ever get all that close to a pig – sweating or otherwise, and I have no plans for the future in that area. Evidently though, someone at some time did get up close and personal with a pig, a sweaty one and told people about it.
“SWEAT LIKE A PIG” – “A PENNY FOR YOUR THOUGHTS” – “CUT THE MUSTARD” – “STRAIGHT FROM THE HORSE’S MOUTH” – “AT THE DROP OF A HAT”
These strange phrases come from somewhere. They don’t just show up in the mail.
