How do I get MRB free tickets to Kimmel Comedy Club

Just saw that there are 2 free tix to the Jimmy Kimmel Comedy Club in the '26 MRB but didn't see a promo code on the 'terms and conditions' online.  
Can anyone tell me what that process looks like?

Thanks in advance - 

Good question. I don't know for sure but since it's based on availability it would appear you just chance it by a walk up to the box office. Maybe Tanya will offer an answer.
