Wikipedia's own random page link drops you into any article in the encyclopaedia with no filtering applied, which is why it lands so often on a Romanian village, a species of beetle or a defunct Scottish football club. Refresh and it hands you another, indefinitely.
The randomness is genuinely uniform, so most results are obscure stubs and stumbling onto a well-written article about something you had never heard of feels earned.
