在网络剧“Going Postal”第一集“A Nifty Trick”中，我们的主角邮差Echo De Mille用自己的超声波狮吼功震退了1只大狗后，被突然冒出来的两个为公司工作的特工企图带走，另1个有缠身能力的Constrictor抱住了他(这能力还能再无聊点么，要能像橡胶人路飞那样还行)，结果再次被他的狮吼功震退，最后跑掉。
下一集“The Houseguest”将于美国时间7月21日在NBC官网播出。
本集的台词：
Postman Echo De Mille is shown running down a street, then between two houses. He reaches a dead end and turns around to face an angry dog.
Echo [to barking dog]: "Whoa, whoa, whoa, whoa! Hey. You're not bothered by the cliche of this: you being a dog, me being a mailman? It doesn't have to be like this. You could just roll over.. I could scratch you belly... [dog continues barking] Look, you had your chance. Now back off! I said BACK OFF!"
He speaks the last word using his sonic scream power, which results in the dog running away whimpering.
Echo [to retreating dog]: "Next time, don't mess with the mailman."
He bends down to pick up his mailbag, when two men approach him. One is in a suit, the other is in a tank-top and jeans and appears to be making serpentine movements.
Agent in suit (Agent Howard): "That's a nifty little trick you've got there."
Echo [recovering his bag and trying to walk away]: "Excuse me. I'm running late."
Agent Howard: "My associate and I have been looking for you, Mr. DeMille."
Echo: "How do you know my name?"
Agent Howard: "We work for a company that helps people like you."
Echo: "What do you mean, 'people like me'?"
Agent Howard: "You have an extraordinary ability. We're going to teach you how to use it."
Echo [laughs]: "You've got the wrong guy."
The snakelike agent (NBC site calls him The Constrictor) wraps his arms tightly around Echo.
Echo: "Get your hands off me!"
Agent Howard: "My friend here is what we call a 'constrictor'. You keep struggling -- he'll keep squeezing."
Echo uses his sonic scream. Both agents fall to the ground, causing The Constrictor to release him. Blood rushes from Agent Howard's ears as he tries to raise his gun.
Echo screams again and runs away as Agent Howard collapses.
The Constrictor crawls over, picks up the gun, and fires two shots toward Echo. He then quickly stands up, pulls out a phone, and dials. Agent Howard is on the ground, bleeding from the head and shaking. The Constrictor shoots him, and his body is still.
The Constrictor [on the phone]: "Bob, Howard's dead. ... Worse than we thought. ... Ok."
The Constrictor hangs up the phone, and looks at an image on the screen of Echo embracing a woman.
The Constrictor: "It's a shame, she's so pretty."
The Constrictor walks away from Agent Howard's body, and the video ends with the HEROES eclipse, followed by credits.
