In the Blood Brothers episode of Seinfeld, Kramer withdraws his blood from his bank. “All you banks are the same with your hidden fees and service charges.” However, he comes to the realization that he needs to deposit his blood back. So Kramer gets some Tupperware, of course, and transports his blood in Jerry’s car. While driving, Jerry’s car starts to overheat. So, he grabs the owners’ manual, and it tells him to turn off the A/C. Well, he’s got blood in the car and it needs to stay cool.
