... functional Captain Kirk chair -

Upon noticing that Sheldon's sad, a police officer, played by
Michael Richards, says that he has a friend named Bob Sacamano who just happens to have for sale the entire original set of the NCC-1701-D bridge... and he'll accept bitcoins.
Backtrackin' a sec, the Michael Richards character arrived late to the crime scene, barging through the apartment door à la Kramer with, "Sorry I'm late, but after tens minutes waiting and pushing the buttons, I finally realized that the elevator is broken." Whereupon another officer (perhaps played by Jerry Seinfeld) pipes up with, "You kept pushing the buttons?" Kramer: "I keep hearing a bell."
Prior to Kramer apologizing, a slightly oversize black officer says, "Hello,
"
Adam Savage opts to not press charges because Sheldon heavily modified the chair for an even better experience which Adam thoroughly enjoys, including Sheldon gifting myriad other magnetic computer cards programmed with all kinds of niceties.
The last scene is Adam Savage back at home sitting in the chair and placing a random magnetic computer card in the slot whereupon he hears Mr. Spock say, "Sheldon, Sheldon, Sheldon."
At the beginning of the episode, Sheldon takes a brief notice of two dudes moving into a once vacant apartment trying to get an oversize armoire through the door. Later, when the chair arrives, he again passes the dudes trying to get the armoire through the door, then shortly realizes that he has the same issue with the oversize chair. Sheldon, being a brainiac, realizes that there's no way he could nor would be able to breakdown the investment nor adjust the size of the door, he figures out a solution via using the window with the help of the new tenants experiencing the same problem. The window solution came to him when a blue jay let on the outside sill and pecked at the window, then flew away.
After Adam drops the charges and the police are getting ready to leave, another police officer arrives late - played by Jason Alexander - carrying (and eating one) a large tray of quesitos (Puerto Rican pastry) given to him by the new tenants on the lower floor of the apartment.
