Welcome to the "name that whatever!" Here you will name where phrases, characters, and other stuff from the Hitchhiker's Guide to The Galaxy.

First phrase:

Name where this was said and by whom.

Radio show. Something about a flying teacup.

Where and whom? :D

Upper atmosphere of Magrathea, bowl of petunias (originally a missile on intercept course)

"The planet in question is in fact the legendary Magrathea.

The deadly missile attack shortly to be launched by an ancient automatic defence system will result merely in the breakage of three coffee cups and a mouse cage, the bruising of somebody's upper arm, and the untimely creation and sudden demise of a bowl of petunias and an innocent sperm whale."

righto :D

To be preciese the bowl of petunias is one of the many incarnations of Agrajag.

Dammit, I wanted to ask that one... >.<
