There once was a zebra who moot

A tomato was really a fruit

MOOT= To bring up as a subject for discussion or debate; to argue. This verb is regular, so the past is "mooted", but here, "moot" is used as a past form (it might be old English).

TOMATO= Notice the British pronunciation here /təmɑ:təʊ/. American pronunciation is /təmeɪtou/ (but both BrE and AmE say potato /pəteɪtəʊ/)
