A joke regarding a person's forhead is: "Berta’s forehead is so big that, when it rains, her clothes don’t even get wet." The forehead is a popular target for insults, due to its high visibility.
Another joke is: "Henry is not bald; his forehead is just so big that his scalp needed to make extra room." In addition, "Erica’s forehead is so big that it has become the best B.A.S.E. jumping spot in all of Kansas!" is also a joke that targets a person's forehead.
Body parts are often the subject of funny and offensive insults. These can range from the plainly visible – such as facial features and limbs – and those that are typically covered, such as private parts.
