The new episode of "The Big Bang Theory" will be nothing short of trouble and laughter. The installment titled "The Graduation Transmission" will inaugurate an allowance-less future for Raj, which he sure hopes would be temporary. 

The astrophysicist finds it best to pay for an unbelievably pricey helicopter toy drone instead of paying his rent. This is where the mayhem commences. Unfortunately, Raj's father finds out and right there and then decides to leave him penniless to teach him a literally valuable lesson. 

Realizing his mistake (the idea sounds so much fun when he first thinks of it), Raj decides to return it to the store to get his money back. Sadly for him, that is not going to happen with Sheldon and Howard already dismantling the expensive toy into a million pieces with the hopes of calibrating it.

Needless to say, there's nothing left for Raj to do than to freak out and panic. How bad can it be though? If Sheldon and Howard easily manage to take the helicopter drone apart into uncountable pieces, they can put it back together to make it look like no dismantling happened right? Raj doubts that. 

Meanwhile, Leonard and Penny have their own dilemma to deal with and interestingly, it involves an aircraft as well. The former is invited by his old high school in New Jersey to deliver an "inspirational commencement speech." Just when the couple is ready to leave, his flight gets cancelled. 

Not wanting Leonard to miss the important event, Penny suggests that he address his speech through Skype instead. She even goes out to get him a cap and gown but she (and more importantly, Leonard) have to settle with what's left in the party store — a "short sexy graduation outfit." 

"The Big Bang Theory" titled "The Graduation Transmission" will air on April 23.
