Okay, all of you know the fast-running avain character Road Runner, who always escapes the bird-craving Wile E. Coyote, right? He always makes the car horn-like sound just to scare his canine predator off of canyons or to attract his attention, and Chuck Jones describes the noise as "the only way the Road Runner can harm the Coyote". But I'm also wondering why on earth would a bird make such a noise, so today I'm going to tell you my different theories on why the Road Runner says "Beep-beep!". Some of them may or may not make any sense but that's okay.

1. The Road Runner has accidentally swallowed a car horn: Based on this picture (link), the Road Runner possibly got his ability to beep like a car because he had swallowed a car horn, possibly from the car named after him. But since the horn is not visible lodged in his throat, then it might have been a smaller car horn.

2. The Road Runner is actually a robot with the ability to make car noises: Although you may not see some nuts, bolts, or metal on this rapid beeper, this is still my theory. How does the robot leave behind feathers while running to make it look like it's a real bird? There is a hidden chute in his body that shoots out the feathers, and his "beep-beep" noise is actually a voice chip self-triggered whenever he opens his robot beak. If this theory were to be in effect, have Wile E. finally kill the Road Runner and only to find out what the bird truly was, he would have no other choice but to mover to other, easier prey.

3. The Road Runner is a swearer: Remember when curse words are bleeped out whenever someone tries to say them. That is also common on Tiny Toons character Fowlmouth, and I think it should be also common on the Road Runner too, because... I don't know. He might say those words out loud just to offend and scare the Coyote at the same time, and they are bleeped out por the "beep-beep" sounds that we always hear from RR.

4. Or, the Road Runner actually says "beep-beep" because he shares voices with his VO: According to Chuck Jones, the Road Runner's uncredited voice artist, Paul Julian, first made the bird's car-like noise because he coud not see where he was going in a crowd of Warner Bros. staff. So, making sense or not, the Road Runner might share the same voice as Julian.

So there you have it, Why Does the Road Runner say "Beep-beep!"?. Like and comment! Right now, all I can say to end this opinion is:

Th-th-th-th-th-that's all folks!
