So I’m on the city bus and a 10-12 year old girl and her mother gets on. A boy of 10-12 years sees the girl, likes what he sees and says:
The girl didn’t respond. My guess is she didn’t know how to. Plus she had to sit with her mom. I didn’t see the mom’s reaction. I also don’t think the boy saw the mom when he spoke.
What impressed me was the earnestness with which he said it and the innocence of “I’m a boy”. Take that away and it doesn’t pack the same punch. Just thought I’d share.
He should have said, “I’m not this tall, I’m sitting on my wallet.” 
I have a friend whose two go-to lines are:
“If you were a booger, I’d pick you.”
And, while approaching with a folded napkin or something similar, “Does this smell like chloroform to you?”
Surprisingly, he’s single. The time that that second line worked, it worked very well, but then he had doubts about whether he really wanted to go on a date with someone on whom that line worked…
Having ‘lines’ helps ensure one remains single.
All the more reason to have as many as possible!
My favorite is one I saw somewhere a long time ago somewhere on the web;
“Baby, you look so good, I’d bang you in front of my wife’s attorney.”
Assuming it’s not too crude, a line works fine as an icebreaker. Of course, the very best pickup line ever devised is, “Hi.”
Personally, this one is my favourite:
And yes, this was actually used on me - though thankfully, it was just the once and was totally done tongue-in-cheek.
(I have to admit, I kind of like the booger line used by Jsb5391’s friend, tho)
Calling it a pick up line was my interpretation.
So it worked, then? 
I’m gonna have to use the chloroform one on my GF. She’s the kind of person who would like it. I wonder what that says…
Years ago, I had an “I’m with STUPID”, t-shirt but instead of pointing left or right, the arrow pointed down towards my pants. I would wear it when I was “on the prowl” at a bar, or such.
It worked several times.
how bout this. Hi, what’s your name? Oh, I love that name.
This is an exchange between my then 6yo boy and a 16yo cutie and her friend at the pool:
Son: “Do you think I’m ugly”
Cutie: “OH NO! I think you’re cute”
Son: “Well, can I have a hug? And can I get one from your friend too?”
[both girls proceed to hug my son]
Me: [wipes single tear drop from cheek]
There’s one I’m dying to use, but I doubt that the right situation will ever come up.
“Are you Catholic? Because you would look so cute dressed up like a nun. Hey, then I could dress up like a priest. We could go to church together, and sit in one of the pews… and totally make out in front of everyone.”
The one I used this morning:
“Good morning! How’s it going?” I notice she’s wearing a string of pearls. “Hey, are those real?” She starts to answer. “The pearls, I mean!”
Back when I was single, I determined that the best pickup line would have to be one no woman had ever heard a man say to her before. So my go-to line became “I’m sorry. It’s entirely my fault.”
My present gf introduced herself to me in the following way:
“Hi, I’m ____. Everybody has been telling me I should talk to you.”
Worked rather well.
My best one was, “You look like you could use a friend. My name is Bob, and here I am.”
Do you want to talk about the weather, love? Aye, whether you’re going to suck us off tonight.
Do you like chicken? Well suck my c0ck, it’s fowl.
Etc…
Was having lunch with some buddies at a food court in a mall,when a particularly beautifull girl walked by and got into line at one of the vendors. One of the guys stared for a bit and then walked over and handed her a five dollar bill. He then used his favorite line.
He told her we had taken a poll about who had the cutest butt in the mall and she had won first place.
Musta worked they are married now with three kids.
Here’s one that, if I were to be the type of person to use a pickup line, I’d totally use.
“You look like my second husband.”
Hopefully, he would say, “How many times have you been married?”
“Once.”
“What was his name?”
“I don’t know, you haven’t told me yet.”
