Bert was showing a visitor to Caltech Geology around the department.

Are you enjoying your visit?

Yes I am, you have some impressive scientific equipment here, we must try and get some equipment like that at Rice.

OK, are you ready for lunch? We can continue the tour after lunch before we get ready for your seminar.

Lunch sounds good, I am feeling hungry.

OK next part of the Caltech tour is the canteen...

##############################

10 minutes later Bert and his visitor are trying to find somewhere to sit so they could eat lunch.

It's crowded today, let me see if I can find us a place to sit. Ah there is a place over there next to Sheldon and Amy.

Sheldon?

Yes, he is only a Physicist, but he's really smart. He's from Texas too.

Texas did you say?

Hello Amy, welcome back, how was the honeymoon?

Hello Bert, would you like to join us?

Thank you Amy, thanks for inviting me to the wedding, I had a great time.

Glad you could make it.

Libby, may I introduce you to my friend Amy Farrah, is it Cooper or still Fowler?

I am not changing my name Bert. Hello I am Amy Farrah Fowler.

This is Professor Libby Henderson from Rice University. Libby this is Amy's husband Sheldon Cooper.

Hello Libby, I see you stuck with Geology instead of a real Science...
