Sir Lance a Little 2

Sir Lancelottle proudly admits to putting up a sign for a secret entrance. Despite his confidence in his intelligence and wit, the speaker expresses frustration about being stuck with him. Who, in their right mind, put the sign in front of a secret entrance that says, Secret Entrance! Huzzah! Does thou knowest that it was I, of course, Sir Lancelottle? With my dashing intellect and cunning wits, we will thwart the forces of evil by the way of said passage." I cannot believe I am stuck with this idiot!
