Easter Eggs

YouTube has had featured Easter eggs on their website in the present and past. This is a list of current and past YouTube Easter eggs.
==Current Easter Eggs==
===Rainbow timeline===
If you type "awesome" while viewing any video, the video's timeline will flash in rainbow. Typing "awesome" again stops it. Certain browsers may not support this feature.
===Small Dog===
On YouTube for PS4, Xbox One, Nintendo Switch, and on YouTube TV, holding rewind (left on a gamepad thumbstick, left or J on a keyboard) for a few seconds while at the beginning of a video, will cause an animated image of a small dog to run across the video's progress bar.
===301 Video===
If you type in "301 video" on the YouTube search bar, the first video in the top results will be permanently stuck on 301. This is a reference to an old YouTube system where after the video reaches 301 views, the view count no longer updates in real time, usually receiving its next update a few hours later. This was apparently to stop bot views from being counted. A temporary bug later appeared on December 2009 which caused the view counts of HD videos to lock up at 301 views or higher, preventing even videos with verified views from showing their real view count on the page. When a video titled "Why do YouTube views freeze at 301?" by a YouTuber named Numberphile appeared, the view counter got stuck at 301 views for the first couple of hours after it was uploaded.
===Seinfeld Without People===
Type “seinfeld without people” in the YouTube search bar, you will find a video without a Title and Description in the search results.
If you watch "Too Many Cooks | Adult Swim", the video's title is displayed in a combination of the Georgia and Serif font, with a similar color and shape to the actor names shown in the intro credits of the video.
===Robots.txt===
There is a little message from the YouTube team if you type “robots.txt” at the end of the YouTube domain name.
===Webdriver Torso===
Web Driver Torso is a YouTube channel that was established on 5th July 2013. The channel has 160K subscribers and more than 620K videos till now. The channel uploaded random videos with blue and red rectangles. Web Driver Torso is also a sound effect in the Audio library in YouTube Studio.
===Technoblade Never Dies===
If you search "technoblade" on YouTube, the suggestion "Did you mean: technoblade never dies" appears, a tribute to Minecraft YouTuber Technoblade and his catchphrase. It works on any device using a web browser, going to the YouTube website, or via the YouTube mobile app.
==Past Easter Eggs==
===Doge Meme===
Searching "doge meme" on the YouTube search bar would change the site's text to a colorful Comic Sans MS fonthttps://web.archive.org/web/20131226192205/https://www.youtube.com/results?search_query=doge+meme, referencing the Doge internet meme.
===Snake===
If you pressed the up arrow on your keyboard while watching a buffering video, the loading circle would turn into a snake, and dots would appear in the video. For the snake to become longer, you would have to make it eat the dots. However, making the snake crash into the video borders or itself would make it disappear. This is a reference to the classic game Snake.
Nowadays, you must type "&html5=1" at the end of the video URL if you want to find the easter egg.
===Do The Harlem Shake===
If you searched "do the harlem shake", the Harlem Shake song would play as the logo moves left and right and after the drop, the whole UI will dance around.
===Wadsworth Constant===
You could add "&wadsworth=1" to a video URL to apply the "Wadsworth's constant", skipping the first 30% of the video.
===Use The Force Luke===
If you searched "use the force luke", the page would start to warp around depending on your mouse's movements.
===Geek Week Look===
It will turn your page into a great retro look. You have to type “/geek week” in the search bar for this effect. 
===Beam Me Up Scotty ===
YouTube gives the classic Star Trek by beaming the videos on the search result page when you type “beam me up scotty” in the search bar.
