No new episode of "The Big Bang Theory" will be aired this week. The CBS comedy has been on a break for the past few weeks and new episodes are expected to be aired only from March 31 onwards.

Season 9 episode 19 titled "The Solder Excursion Diversion" will see Howard and Leonard working together on their app, and Sheldon revealing something shocking to Amy.

Warning: This article contains spoilers of the March 31 episode of "The Big Bang Theory."

A leaked description of the episode on Wikia states that the upcoming episode will see Leonard and Wolowitz lying to their wives and ditching them for a movie premiere, which has Will Smith in attendance. Instead of coming clean to Penny and Bernadette, they lie about having a flat tire. They even text Raj and tease him about missing Will Smith.

Elsewhere, Amy will realise that her boyfriend Sheldon is a hoarder after he refuses to throw away his damaged laptop. Sheldon reveals that he keeps all unwanted stuff in a storage unit and makes Amy sign a non-disclosure agreement before taking her there.

The synopsis for "The Solder Excursion Diversion," according to Wikia, reads: "Amy is shocked at a revelation from Sheldon after she buys him a new laptop. Also, Koothrappali sells out Leonard and Wolowitz after they lie to their wives in order to attend an early screening of a movie."

In other "The Big Bang Theory" news, Jim Parsons aka Sheldon recently revealed during the annual PaleyFest panel that he would like Sheldon and Amy to hit the sack again. Recalling his favourite scene so far in the season, Parsons said he loved Amy and Sheldon's after-coitus moment.

"I will tell you, my very favorite thing so far has been the after-sex scene with Amy and Sheldon," Parsons told Glamour. "I just had never had the opportunity to relate to anybody in that kind of way on the show, like a pillow-talk scene. I was like, 'There's a whole other way to talk on this show that I didn't have access to before!' We haven't been back in the sack since then, and I'm hoping to get back there."
