That's cool, I like it. I do cheesy stuff like that all the time. I'd keep her guessing whether I'm serious or joking though.
You can't keep it up for long, you've gotta start making interesting chat with her early on.
Only once I told a girl she's like the girl in Pretty Woman (wasn't an opener) and she replied "are you saying I look like a prostitute?" I just laughed and apologized (some "alpha" wannabe probably thinks that's weak). Nothing ever happened with her but we're good mates now.

"haha! seriously though. I'm not that lame." Give a cheesy grin, then move to natural conversation. Just be light free and confident. Make her leave you or close her quick then eject.
I wouldn't verbalize that you're joking. It's something I used to do a lot, but I've found it SO much more effective to sub-communicate it.
Maybe just a cheeky smile, and a facial expression that says "are you really that gullible?" and then start talking about something serious. It shows that you don't take yourself too seriously, and that you really aren't concerned about what she thinks of you. It makes you appear really secure.
