Theres a spin-off show I would watch in a heartbeat.

Come on, Chuck Lorre.

ThisBig Bang Theoryepisode was all about blasts from the past.

Who wants a job selling menus?

Penny is intrigued especially since she doesnt love pharmaceutical sales.

Is it really a good idea for Penny to consider working for her ex-boyfriend?

I just want you to be smart.

Pennys translation: Leonard thinks shes dumb.

Leonard tries to get Raj and Howard to agree with his side, but neither does.

Both assume Penny is going to leave Leonard sooner or later.

It might as well be now, right?

At the same time, Penny informs Bernadette that she thinks its weird that Leonard is so jealous.

Bernadette, like the rest of us watching, has no trouble believing that at all.

It seems Zacks fiancee doesnt want him working with his hot, blond ex-girlfriend.

Like Leonard, his better half thought the idea was stupid.

And Zack has the bump on his forehead from the shoe she threw at his face to prove it.

He must do things that make his brain uncomfortable.

First up is a homemade batch of croissants.

Of course, Dr. Cooper masters the flaky, buttery pastry.

Unfortunately, he develops a severe case of jugglers elbow and moves on to the unicycle.

That goes nowhere, thanks to all cycles being dumb.

(Uni-, bi-, tri-, menstrual… take your pick.)

He nods and runs off to find some stilts.

Surely Bernadette has a male version of Tammy Jo stuffed in a box somewhere, right?

Sheldon as a ventriloquist has season finale written all over it.

Theoretical Laughter

ZACK: Sheldon is like the Swedish Chef Muppet.

I dont know what hes saying, but hes funny.

HOWARD: The circus arts are physically and mentally demanding.

Have you ever tried to juggle?BERNADETTE: Yes.

Im juggling my love for you and embarrassment of you right now.HOWARD: Its hard, isnt it?

SHELDON: Physicist, baker, lover, what cant I do?
