What do you do when you're a happily married superstar?

For Jay Chou, he's spending his time collecting unique tennis rackets.

He shared in an Oct. 4 Instagram post:

I'm recently obsessed with finding weird and rare tennis rackets on the internet. If anyone has seen really cool and limited edition ones on the internet please post them on your page and mention my account [in the caption].

I'll have a look and see if there are any that I've never seen before. I'll pick those and give you concert tickets. What do you think?

In the hashtags, he added:

• He's seen "a lot" of unique rackets
• Antique ones don't count
• Customised ones don't count either

You know what to do.
