Ted's greatest hits

Hi everyone,

Hi everyone,
What does" Ted's greatest hits" mean in the following conversation?

In the TV show "How I met Your Mother"

Ted was talking about his feelings of love resurfacing for his ex girlfriends.

Ted: What if there's someone from my past who I thought was wrong for me at the time, when in fact, she, like this shirt, is actually a perfect fit?

Lilly: this isn't a bad idea. Let's think. Ted's greatest hits. What about that girl, Steph?

Thanks a lot in advance.
