"nun" joke

Once there was this nun in a church. One day while
taking a shower she heard a knock at the door.
Since there was no one who could answer the door she
yelled "who is it" the man at the door replyed
" the blind man " The nun thought since it was a
blind man she could open the door, and so she did.
The man answered " good gracious where do you want
the blinds?. "

For people who didn't understnd that, the man at
the door was the blind fixer.!!!
