Based on this video, it seems clear Leigh Lahav loves two things very much: her husband Oren... and television.
Leigh put together this compilation of re-created TV show intros for Oren's birthday, and it looks like it took a lot of work.
The shot-for-shot recreations are uncannily accurate, with people and details from Oren's life (or sometimes just his first name) cleverly replacing the originals.
Pretty great birthday surprise - but as one comment on YouTube pointed out, it's a lot of pressure on Oren when Leigh's birthday comes around.
If you're keeping track at home, the shows in question (as listed in Leigh's video description) are:

2 Broke Girls
