How can anyone forget that he had sex with Penny?

I picked up a very useful life lesson from Rosemary's Baby; never go with a hippie to a second location.  Wise words, indeed.

Except Lily just tells Ted that the bride wants to see him.  She does not explicitly say Robin's name.

Him following her home must have been the thing to do.  Both of my grandfathers followed their future wives around on the street before getting the nerve to talk to them.  Both of my grandmothers were fully aware they were being followed.  This was pre-WWII.  It made for some sweet "how we met" stories.

Not all Americans are unaware of various British actors. I know Bill Baiily mostly from Black Books and giggled when he appeared on screen.  You should get your British comedy hat on. Netflix is your friend.

Me three.  I couldn't have been more than 11 or 12 at the time.
