An old woman goes to visit the doctor and the Doctor asks her what the problem is.
"Well Doctor, it's my husband. As you can imagine, we are getting up there age wise and we don't make love nearly as often or as intimately as we used to. It seems like it's been years! I was wondering if you had anything to help?"
"I have just the ticket," the Doctor replies. He head over to his cabinet and grabs a bottle of elixer. "Here, add a couple drops of this to his coffee and believe me, he'll go WILD."
She takes his advice and heads on home. A week later, she comes back to the Doctor's office for a follow up.
"So, how did the elixer work?"
"Oh Doctor, it was awful!" She replied.
"What!? What happened!?"
"Well, I did exactly as you instructed and I put a couple of drops into his coffee. He took a sip, immediately got a look in his eye, jumped across the table and ravaged me on the floor! He just kept going and couldn't stop! I can't remember the last time he made that kind of passionate love to me."
"What's the problem then?" The Doctor asked.
"Well," she replied, "we aren't allowed at Starbucks anymore."
