Along with the Sister Paine in the rear legend / joke, there was the legend / story about the "brother" saying a concluding prayer at a meeting and asking Jehoober to forgive our "falling shorts".
We DID have a Sister Payne, in our Confregation and every Pain/Payne remark possible, was made including the Payne in the rear joke. in fact, she "Payne-stakingly" made a point of not sitting in the back of the hall for that reason.
We've all heard the one where supposedly after the Sunday talk the Chairman said " Thank you for that fine talk Brother Jones...and now while the microphones are being set up, we'll have a five minute intercourse" (he mixed discourse and intermission together and came up with intercourse)
I've told the story of how my Mother used to be the Piano player at our Hall. For that reason we always had to be to the meeting on time. One time she was in such a rush to get dressed that she put her coat on right over her slip. She dashed up to the front of the Hall as soon as we walked in and it wasn't until she had her coat part way off that she realized she wasn't wearing a dress. We never let her live this one down.
