The search is on!

Who knew that a quest to find something as nerdy as Bitcoin could be so much fun?

Was it just me, or did Mrs. Wolowitzs bellowing make you feel all warm and fuzzy inside?

The Bitcoin Entanglement

It seems that a single Bitcoin is worth five thousand dollars.

The guys are eagerly shocked since they mined Bitcoin seven years ago.

Sheldon complained about an inevitable hassle with the IRS, so the others kick him out of the group.

Howard digs out his old laptop while Raj dreams about buying a tiger with his newfound cash.

Unfortunately, the Bitcoin is not on the laptop.

Its back to 2010, and we see Howard at his computer with Raj and Leonard close behind.

Present-day cheers all around!

Leonard gave that computer to Penny.

The guys interrupt a very important wedding planning conversation between Penny, Sheldon, and Amy.

Who cares if Sheldon thinks a cliffside wedding is both too cliffy and too beachy?

They need to cash this coin and see a man about a tiger.

Penny sheepishly confesses that she gave the laptop to Zack.

Tall, dark, handsome, and dumb as a bag of rocks?

Flash back to 2010.

Leonard lets Penny have his computer since hes getting a new one.

Penny gives it to Zack during one of her breakups with Leonard.

In the present day, the guys attempt to piece the timeline together.

Was this the St. Valentines Day breakup?

Penny calls Zack, who thankfully still has the computer.

Because you never give away anything away someone so special gave you.

In fact, he has a video about how much she missed Leonard when they were broken up.

On that very computer.

Having Hofstadter as a last name doesnt help.

Who can remember where the D goes?Amen, sister.

Penny and Leonard finally get back to the apartment with the correct laptop.

Howard announces that the Bitcoin folder is empty.

Sheldon pops up, giggling at his clever revenge.

He downloaded the Bitcoin on the Batman flash drive that Leonard carries around on his keychain.

The same keychain that Leonard lost several years ago.

He just cant come up with one right now.

Theoretical LaughterPENNY: I cant believe youre mad.LEONARD: Im not mad.PENNY: Oh really?

Tell that to your eyebrows.
