A middle aged woman has a heart attack and is taken to the hospital. While on the operating table she has a near-death experience. During that experience she sees her guardian angel and asks if this is her time. The angel says no and explains that she has another 30-40 years to live. Upon her recovery she decides to just stay in the hospital for a few more days and have a facelift, liposuction and a tummy tuck. She even has someone come in and change her hair color. She figures since she's got another 30 or 40 years she might as well make the most of it. She walks out the hospital after the last operation and is killed by an ambulance speeding up to the hospital.
She arrives in heaven again, sees her guardian angel and says, "I thought you said I had another 30-40 years!!"
The angel replies, "Sorry. I didn't recognize you."
