A baptist deacon had advertised a cow for sale. "How much are you asking for it," inquired the buyer. "A 150 dollars" said the deacon. "And how much milk does she give a day?" asked the buyer. :4 gallons a day" he replied. "But how do I know she will actually give that amount?" asked the purchaser. "Oh you can trust me I am a Baptist deacon". said the man. "I will buy it" said the purchaser "I will take the cow home and bring the money back later. You can trust me I am a Presbyterian elder." When the deacon arrived home he asked his wife "What is a presbyterian elder?" "Oh," she said, "a pres elder is the same as a baptist deacon." "O dear I have lost my cow" groaned the deacon.
