Shrinking Man Seeks Humorous Diagnosis

A man goes to the doctor and says, "Doctor, I think I'm shrinking!"
The doctor responds, "Don't worry, you'll just have to be a little patient."
The man groans and says, "That's not funny."
The doctor shrugs and replies, "Well, at least you'll be able to fit in smaller spaces now."
The man sighs and says, "I guess you could say I'm feeling a little shortchanged."
