Periclinal

A four-panel comic. Panel 1: An excited man with long hair and a beard exclaims that you can buy periclinal chimeras—plants where different tissue layers are actually different organisms in the same tree—while a woman with glasses stands behind him looking unimpressed. Panel 2 (labeled LATER): The man tells two kids the big news that the mythical creature he ordered has arrived. Panel 3: The two kids cheer 'YAYYYYYYYYYYY!' Panel 4: The man triumphantly holds up a small, scraggly potted plant, explaining it has the mesophyll and vascular tissue of a trifoliate orange and the epidermal tissue of a satsuma orange; the kids slump in disappointment, groaning 'NOOO.' The joke: a botanically fascinating chimera plant is a total letdown to children expecting an actual mythical creature. Votey (labeled IN REALITY): A close-up of a tired old man's face, half asleep, saying 'IT'S A PERICLINAL- WHY IS EVERYONE ASLEEP?'—implying the speaker is a boring know-it-all whose botany lecture puts everyone to sleep.
