Well, aren't we funny.

I'm at Nordstrom and I'm buying some pantyhose. I'm holding my wedding dress, which I've just picked up from being altered.
Cashier: "What's the gown for?"
"Oh, it's for my wedding!"
Cashier: "Oh, how exciting!"
"Yeah." awkward silence... I decide to inject a little levity into the moment: "I'm more excited to wear these (pantyhose) with some cream pumps!"
Cashier: "Well, aren't we funny."


Is there any way to take "Well, aren't we funny" as a positive remark? I mean, she didn't say it insincerely... but wtf.
