A man is giving a speech at his lodge meeting. He gets a bit carried away and talks for two hours.

When he realizes hes been talking for so long, he gets very flustered, and continues for another hour.

Finally, he manages to regain his composure. Feeling certain hes bored or upset, and lost, most of the audience, he says, Im sorry I talked so long. I left my watch at home.

From the back of the room comes a voice. Theres a calendar on the wall right behind you!
