An Irish woman of advanced age visited her physician to ask his advice in reviving her husband's libido.
'What about trying Viagra?' asked the doctor.
'Not a chance', she said. 'He won't even take an aspirin.'
'Not a problem,' replied the doctor. 'Give him an 'Irish Viagra'. It's when you drop the Viagra tablet into his coffee. He won't even taste it. Give it a try and call me in a week to let me know how things went.'
