In 2004 I went to Vegas with girlfriends. I was hungry and they would not stop long enough for me to grab a burger and a beer. Finally, we stopped at a hotel cafeteria where the patties are pre-cooked sitting in a pan of water then reheated. Gross! I continued to request a decent burger this time. We found one at Jimmy Buffet's Margaritaville where I had a satisfying burger. It did drip onto my shirt and maybe squirted some juice onto them. That may have contributed to a shopping trip at the mall where the staff will bring you a beer in the dressing room if you so desire.
A year or so ago my husband, lover of a decent burger, and I cooked some burgers and I opened the mustard cap which had some crust around the little plastic hole. It fell right onto my burger! I said "I just got the mustard crust from the cap on the bottle" and thought to myself......"self,....sounds like a song here".
I happily included the ketchup on the white shirt which actually happened to my niece Katherine at a restaurant! When I sang the song she laughed and knew right about that part was about her!
