The Pope is dying of some unknown disease... and after seeing many many specialists they finally found one...

...that could diagnose the problem. The specialist lets the head Cardinal know the problem, all cardinals confer then go and speak with the pope.
"Your holiness, after talking to the specialist, the only way to save your life is you must have sex with someone."
After much thinking and debating, the pope finally agrees, but says he has three stipulations.
"One, she must be blind so she cannot see who is having sex with her."
"Yes, next?"
"Two, she must be mute so she cannot say who she had sex with if she figures it out."
"Yes, you holiness. And your last stipulation?"
"Big ol' titites."
