Broccoli is a social construct - Mug

Broccoli was bred out of wild cabbage by humans, for humans, according to human preferences. Technically this is one of the strongest constructivist cases available. Wrapped around a glossy mug for the eleven minutes a day you are honest. Equally suited to strong coffee, weak tea and evening whisky.

• Print that stays put: The design will not fade out after a fortnight of washing up.
• Absurd but arguable: The joke survives scrutiny, which is why people keep bringing it up at dinner.

Everything is constructed. Some of it is also a vegetable.
