If it's just a small little bug or spider, I just squish it in my hand. If it's something bigger, like a huntsman, a nice thick book normally does the trick!
Soft hands, Partridge, soft hands. Docile (read dehydrated/aging) huntsmen can easily be relocated with a little patience and tender hands. If they're already aggressive -ie, rearing up- then I'll fetch the ol' mug and cardboard, or chase them back to the roof.

I wish it was a "C" party.. that way I could dress up as a Cop. How can I change Cop, into something starting with B.... Policewoman... no.... Pig.... no.... Detective.... no....
A London BOBBY, my handcuff-loving dear.
Just polish your Polly Page.
I know, I can be Stripey for a night and be a BOUNCER!!!
Woot, I can act like a prick aaaaaall night and start fights.
Crowd Controller, like Cop, begins with "C", Shell.

Why don't you dress as our mutual acquaintance, Betty B? Leaving your gob hanging open all night'll at least shut you up.
A Blues Brother? C'moooooon, Boromir or Bobba Fett, you know you want toooo.

Another Betty B, Betty Boop? Being among strangers rules out Breasts and Buttocks. Playboy Bunny, boxer, brickie, bogan?
Budha Hocking, if you've a 32 jersey? As a Shanrock, I love Eliza's suggestion, you could borrow her 17.
Oh, oh...Bronwyn Bishop!!! Mmmmm. But I insist on pics!
