Slings and Arrows

[sn4fu.livejournal.com]

I know, I'm one of those terrible gals that pops in and out only when she's got a stupid question to ask. Humblest apologies to begin with. Seeing as I'm still plugging away at that Wodehouse research paper I mentioned quite a while back, I was wondering if any of you could help me place this quote:

"...if the slings and arrows of outrageous fortune want to crush his proud spirit, they have to pull their socks up and make a special effort."

I know it's a Bertie Wooster, but I can't for the life of me figure out where it came from.

Thanks!
