How do I get my girlfriend to knock off this annoying habit?

How do I (male) get my girlfriend (female) to knock off this annoying habit she has?<br><br>&#x200B;<br><br>She is a great girl, I’m really in love with her, we’ve been going out almost a year and I think I’m going to ask her to marry me soon. She has a lot of great qualities. But she has this annoying thing she does that happens almost every day and it’s really starting to get on my nerves.<br><br>Almost every day she says something like this to me:<br><br>“Yeah, but if you’re wrong, you have to do anything I want for the rest of my life.”<br><br>Or<br><br>“Yeah, but if you’re wrong, you have to do anything I want.”<br><br>Or<br><br>“Yeah, but if you’re wrong, you have to do anything I want for the rest of your life.”<br><br>Or<br><br>“Yeah, but if you’re wrong, you have to do anything I want for the rest of your life.”<br><br>Or<br><br>“Yeah, but if you’re wrong, you have to do anything I want for the rest of your life.”<br><br>It’s really annoying, and I don’t like her thinking she can threaten me like that. I’m not sure what kind of penalty I would have, but I assume it would be something bad.<br><br>For example, we’ll be talking about something and I’ll say something like this:<br><br>“Oh really? What goes on at your work all day?”<br><br>And she’ll say:<br><br>“Oh nothing. But if you really want to know, you can go see for yourself. But if you’re wrong, you have to do anything I want for the rest of your life.”<br><br>Or I might say:<br><br>“Do you want to go to that new movie that just came out?”<br><br>She’ll say:<br><br>“Yeah, but if you’re wrong, you have to do anything I want for the rest of your life.”<br><br>Or I might say:<br><br>“Do you want to go to that new movie that just came out?”<br><br>She’ll say:<br><br>“Yeah, but if you’re wrong, you have to do anything I want.”<br><br>Or I might say:<br><br>“Do you want to go to that new movie that just came out?”<br><br>She’ll say:<br><br>“Yeah, but if you’re wrong, you have to do anything I want for the rest of your life.”<br><br>Or I might say:<br><br>“Do you want to go to that new movie that just came out?”<br><br>She’ll say:<br><br>“Yeah, but if you’re wrong, you have to do anything I want for the rest of your life.”<br><br>Or I might say:<br><br>“Do you want to go to that new movie that just came out?”<br><br>She’ll say:<br><br>“Yeah, but if you’re wrong, you have to do anything I want.”<br><br>I don’t know what she means when she says I have to do anything she wants if I’m wrong. Does she mean that I’d have to go to that new movie that just came out?<br><br>I also don’t know how she’ll know whether I’m wrong or not. I don’t think she’s talking about some kind of mind reading thing. Unless she is.<br><br>It’s really annoying too because it’s hard to get mad at her when she says things like this, because she’s usually being pretty nice to me when she says it. Like, say we’re going to the movies. I’ll ask her which movie she wants to see and she’ll be all like:<br><br>“Oh, honey, you get to choose. But if you’re wrong you have to do anything I want for the rest if your life.”<br><br>Or, when we were at this restaurant she wanted to go to, and I was asking her what she wanted to eat:<br><br>“Oh honey, I don’t care what you order. Just surprise me! But if you’re wrong you have to do anything I want.”<br><br>It’s not really a big deal, I understand that. It’s just annoying. I’m hoping it’s just a phase she’ll move past as she gets to know me better.<br><br>Or maybe I'm wrong. If so, I guess I'll be doing anything she wants for the rest of my life.
