I Love Erma

Erma was complaining to her friend, Elephant, that it was raining outside, and since she had to go out, her only choices were to get wet or look dorky (which, of course, isn't really a choice. the obvious answer here is get wet).
Elephant heaved a big sigh and said, "Erma...you have-"
"More issues than a magazine. I know," Erma interrupted.
Elephant said, "I was going to say 'more problems than a math book,' but your answer fits better."
Erma said, "That's because people tell me that all the time."
