Levelling up is always fun. In many games you get to choose cool new skills to learn, or existing skills that you want to improve on. Of course it makes sense to pick a skill that you think will come in handy in the near future.
So, GMs, next time your PCs are about to level up, make sure the players know that the next major challenge their characters will have to face is a winner-take-all, to-the-death, flower arranging and poetry competition against the campaign's major bad guy.

GM: That was really good roleplaying last week, everyone. Corey, great work, you got bonus XP.
GM: Luke, R2-D2, C-3PO, Obi-Wan, and Darth Vader all levelled up.
{Han has a sad face}
GM: Oh, I almost forgot.
GM: And Chewbacca.
Luke: Cool! I'll take some Acrobatics skill.
Han: {happy again} What are you taking, Annie?
Darth Vader: You will see.
C-3PO: Bluff! Bluff! Bluff the stupid clones!
R2-D2: Let me double check my character progression spreadsheet...
Obi-Wan: I'll put points in Mechanic. I can see we're going to need that on the Falcon.
R2-D2: ... ah yes. Moar Hacking!
Han: And what about Chewie?
Chewbacca: <sigh> Escape Artist.
