"Amy kept in hospital for further tests"

Stop it! Stop it!

It reminds me of this exchange:

DOUGAL- Father Stone's been in there a long time. Do you think he's dead?
TED- Dougal! No, they're probably just... keeping him in for tests.
DOUGAL- What kind of tests? General Knowledge?
TED- No, medical tests!
DOUGAL- Sure, what would Father Stone know about that?
