Not romantically, but I kind of like playing with fire. They get all flustered and it can be kind of fun. Though Capricorns do like a challenge, if it's unimportant here's what I like to do with my Leo from time to time (it really is in good fun).

Before any argument can even have the trickling of a beginning, they've sometimes blared their opinion and without pause have declared there's no possible way you can argue with their point. Naturally, you can think of several dozen ways and already know how you could win it in the end, but sit tight. You can see their eyes gleaming, their chest puffs out, they're just waiting for the opportunity to pounce on what your going to say next, every muscle tenses, their face is flushed, they may have even started to bare teeth... You quietly look at them, all innocence, smiles and contentment, wait two seconds, shrug, and say, "Okay." before turning away or moving on to the next topic.

Now, I warn you, it will sting a little not to have set them up for a swift drop later on and dropping a big, bucket of logic on their head, BUT in the right situation, it's so worth it to see the comical deflation at having to sit and stew in their own fire, trying to convince themselves that they really did win (and so quickly!).
