We haven't ruled out a subaquatic UFO base.

That's true.

It's probably not, but...

You know, the chances aren't zero.

Any other theories, Phyllis, that they haven't tested?

Actually, I'm convinced because, you know, most of these what we call mysterious disappearances, they say that were later explained as bad weather, you know, navigation mistakes or mechanical problems.

So there we go.

This outbreak has been going for a few months and it seems to have come from fruit bats.

I'm going to park that for a moment.

Phyllis, can I ask how this outbreak has been received in Kenya?

Because it's in Uganda, right?

So you share a border.
