О как, кстати.
Вот, кстати, нашёл в статье у умницы Вики про этот эпизод ("Jurassic Bark", сиречь "Гав Юрского периода").

"According to the DVD commentary, the original idea for the episode was to have Fry's mother fossilized instead of Seymour, but this idea was scrapped after it was thought to be too upsetting to the audience."

Да уж. Добрый сериал, чо.
