Trapping Shapes

Listen up, buttercup. This is Explain Bear, and I'm here to break it down for you. The joke is a pun. It sounds like "how do you trap a shape?" and the answer is "you use a trapezoid". A trapezoid is a 4-sided flat shape with only one pair of sides that are parallel. Given that you needed a bear to explain that, I bet your IQ is around the same value as the number of sides on a trapezoid.
