My dad is a health care professional and recently had a patient that has been “huffing Freon for the past 18 years.” His response?
“I wonder if he gets really bad brain freeze.”
Friend's mom was talking about the high cost of her BMW's repair. "It was $1,500! For the freon!"
Friend's dad "Well nothing's fre-on a BMW!"
The two of us doubled over laughing; no one else caught it.
