It's easy to find canned material with video's on youtube. Chance's are you've probably heard some before
"You look like trouble"
"Are you one of those girls that takes forever to get ready or do you just look like it?"
"I need a female opinion on...whatever"
"Does this shirt make me look gay?"
I mean hell you could walk up and ask the girl if she preferred hot shower's or cold shower's and probably pull. From my experience (the bit that I have) it doesn't really seam to be what you say as long as you're not a complete asshole about how you say it. I believe you just want to sound genuine/original and have an outgoing, playfully fun attitude with an assertive side. Make sure you stand up straight with your chin up and look her in the eye's when you talk and once conversation is started I usually try to show that I'm relaxed by leaning on something. I haven't approached in years I just came out of an almost 4 year relationship and to be honest I've found myself facing approach anxiety but I have done cold approaches before and usually 30 sec's into it I don't feel it no more but lately I can't get up the nerve
But to answer your question yes there is canned material all over the internet
