I went outside for a cigarette a couple of minutes ago, and mid smoke a swarm/herd/*insert appropriate collective noun here* of bats flew right past my face
It was the closest I've come to weeing myself for quite some time.
I don't mind a bat or two, but I like to expect them, not suddenly have loads of them swoop past me like that with no warning.

Anything almost scared the wee or something else out of you lately?

I think bats should be fitted with sirens.
