Identity pun

Sorry guys, this will make you cringe but I can't help myself: this came out while I was reharsing a presentation just minutes ago. Ah, and you'll get it only if you're identity-sick :-)

A passive client enters a shop, and starts looking around.

A salesperson approaches: "Sir, can I help you?"

And the passive client: "Just browsing." 

hehehee :-) In hindsight, it looks so obvious that it seems strange that nobody came out with it: the quick search I did on the core of the joke didn't yield any results, though.

OK ok, back to work...
