You don't get it. I think the guy might just be using the pick up lines for the sake of it's being ridiculous and trying to be funny with it. Not that he's depending on it to pick up the girls. I don't believe in pick up lines but I think it's ok if it's used as a form of humor; I think most of the time the girls are already gonna know how lame it is. I think it's all in the delivery not the content per say.
I get what he is trying to do but to me it seems counter productive to even use a pick up line even as a form of humour. The only pick up line I would even consider using is the polar bear one because it's not about getting in her pants or puts her on a pedestal in some way. Humour is awesome to use as long as it doesn't put you in a negative light.
The basic signal I think that he will be sending with the initial line is that he is socially inept, and then he tries to move away from that by saying "I am only kidding, (seems a bit to apologetic)...."
If I were to use a pick up line in the way that the OP intends to, I would not follow it up with something apologetic. I would say something like "I am competing with my buddies to see who could deliver the cheeziest line, blah blah *insert joke* *throw in a compliment or two* + 1 more joke, get the #(dance) and *continue having a fun night.*"
The other reason I said what I said is because this guy is thinking way to much. You don't consciously command your muscles to take a bite out of a steak when you are eating, so why let "thinking" get in the way of "doing" when it comes to another basic need such as meeting women?
I do believe it is all in the delivery as you do, but if the guy focuses on the feeling instead of how he is going to deliver a cheezy pick up line, he'll do much better.
