Get one for her and ask her if she’s ever experienced four fingers and then when she gets all offended just bust out the candy bar and tell her to get her mind out of the gutter
Years ago I bought my son some candy that he wanted. He unwrapped it and it was exactly like an erect dick. I grabbed it and took it back to the store and got a refund and gave the cashier an earful. Haven't seen that candy since then.
