In T2, the Terminator gets its leather clothes from a biker bar. In T3, he does it in a strip club... with hilarious results.
T-850: Take off your clothes. Gay biker: Patience, honey. (The Terminator walks up on stage, driving the bachelorettes wild) Gay biker: Whoa, bitch, wait your turn! T-850:Your clothes. Gay biker: Talk to the hand! (Terminator grabs it) AAAH!! T-850:(talks to it)Now. (The Terminator walks out, fully clothed, with the bachelorettes wooing him)
Followed by the Call Back to the second film when the Terminator slowly pulls the shades out of the pocket of his jacket and slips them on... revealing them to be a sparkly pink pair with star-shaped frames. One Beat later he pulls them off, drops them on the ground and treads on them.
When Kate finally gets her hands on a gun and points it at the T-850, who, of course, is not concerned. In a panic, Kate pulls the trigger. The T-850 spits the bullet out of its mouth (revealing completely unscratched teeth), much to Kate's horror. The T-850 then just says: "Don't do that." and turns away.
Dr. Silberman, who was a psychiatrist in T1 and head of the asylum Sarah Connor was put in in T2, is sent by the cops to calm Kate in the cemetery. The funny bit was when he tried to assure Kate that it was just her minds playing trick regarding the Terminator.... But the moment he saw that exact same Arnold face he saw years ago in T2, he immediately bailed, as if saying "Oh, No... Not Again!!".

After the Terminator tosses his ruptured power cell and causes a mini-explosion in the desert that rocks the truck they are driving:
T-850: When ruptured, the fuel cell becomes unstable. Relax.
Kate:[in the back] Help! Get me out!
The Large Ham acting of the guy John rear-ends with Kate's truck.
Two from the outtake reel; when the T-850, John, and Kate are making their way through the CRS complex, T-850 is leading the way - puffing on a cigar. And when T-850 and the T-X charge at each other before their fight scene, they stop - and waltz. The smiles on their faces, almost as if to say, "Oh, lovely to see you here," is what really sells it.
After John, Kate and the T-850 escape from the T-X:
