Madge: “I got a call from Burl last night, she talked on and on and on about her Iguana and quilting club. I ended up putting the phone down, making dinner going to the washroom and coming back to hear her still going on about Roe vs. Wade! She never paused or had me speak once!”

Gwen: “What a yakasaurus!”
