Just watched Trivia no Izumi on Fuji TV.  One entry was about seiyuu.

The entry said Tarako, seiyuu of Chibi Maruko, once ate Tarako Riceball,
fell ill, and was admitted to hostipal.

They interview Tarako about the event.  Tarako's normal voice is just the
same as Naruko's !!!

They then showed a short clip of anime showing the details of the event.
That clip is made by the anime staff of Chibi Maruko !

The entry got 74 "hee", IIRC.
