A pastor went to the dentist for a set of false teeth. The first Sunday after getting his teeth, he preached for only eight minutes. The second Sunday, he preached only 10 minutes.

But the following Sunday, he preached nonstop for nearly three hours… until the congregation realized he couldn’t quit, and finally helped him sit down. Concerned for his health, they asked, “Are you okay? What happened?”
The pastor explained, “Well, the first Sunday with my new teeth, my gums were so sore I couldn’t preach longer than 8 minutes. The second Sunday, I felt I could go a little longer to 10 minutes. But, today, I mistakenly put my wife’s teeth in, and discovered I couldn’t shut up.”
