An old lady goes to the doctor and says
‘Doc, I can’t stop farting. They’re silent with no smell, but I’ve let out 20 in the past 5 minutes sitting here.’
The doc gives her some pills and tells her to come back next week. She comes back and says
‘Doc, I took the pills, the farts are still silent but now they stink!’
The doc says :
‘Great! We’ve cleared your sinuses, now let’s work on your hearing!’
