what that wet stuff coming from the sky is. Has anyone got any ideas?

Condensation from the air conditioner upstairs.

perhaps the mangled bodies of Afghan refugees clinging to the fusilage of one of the aircraft escaping to Canada.

?

Yeah, stuff got bad really quickly in Afghanistan.

The air conditioner upstairs must be way upstairs... Not sure I'd want to hike up there.

Arbieroo, something like that I think.
