'The Big Bang Theory' Season 9 Episode 6 Spoilers: Sheldon And Leonard Meet A Black Market Dealer

Yet another interesting and fun-filled episode installment is coming this week as the ninth season of CBS' hit sitcom, "The Big Bang Theory," continues. The segment titled "The Helium Insufficiency" is expected to see the two geniuses, Sheldon and Leonard, meeting and making a deal with a black market dealer. Meanwhile, Penny and the gals help Amy find a new man.

Citing the synopsis provided over at The Futon Critic, it is indicated that the whole country will be experiencing some widespread shortage of helium. Leonard and Sheldon, who are currently in the midst of their experiment, needs exactly that element to complete their work. Out of desperation, as the summary suggests, the pair will take a trip to meet a black market agent to make some purchases of the substance.

Taking further hints from the promo teaser shared over at the International Business Times, it appears that there will be some trouble making a deal with Kenny, the shady dealer.

"Hi, I am Leonard, this is my friend…" Leonard said and then got interrupted by Sheldon, who makes an effort to keep his identity hidden as he tells Kenny that he's "Skippy."

More hilarity ensues when Kenny begins to suspect that the two are up to no good. "No money, no helium," he said while adding that the deal was going nowhere.

"Not necessarily!" Sheldon points out. "You can kill us. Really, you're only limited by your own imagination."

Sheldon's quirkiness baffled the dealer but Sheldon's companion appears to be scared. "What are you doing…Skippy?" a tense Leonard asks.

Meanwhile, the new episode is also expected to see Penny and Bernadette helping out Amy's broken love life by installing a dating app on her mobile phone.

Find out how these events turn out when "The Big Bang Theory" Season 9 airs this Monday, Oct. 26, at 8 p.m., on CBS.
