Special Needs

Listen up, buttercup. The joke is kinda like a self-deprecating confession. Stephanie is saying she's got special needs, implying some kind of disability or difference. And then she hits you with the punchline: she was "born with it." It's funny 'cause it's so blunt and simple. Like, duh, Sherlock, if you were born with special needs, then yeah, you were born with it. What else would you be born with, your looks?
