On this program , we give examples and notes on usage . And when available , we sometimes explain where they come from . On today's program , we are going to talk about rabbits . Rabbits , like many other animals , dig holes and complex underground passages , like tunnels , to build their homes . So , when rabbits want to go home , they must go down the rabbit hole . And that may lead to other holes , tunnels , and paths , or even other rabbit homes . The Internet is an easy way to get lost down the rabbit hole . The animation was so beautiful ! I had to find out more about who drew the images for the game . A few more clicks led me to a website about learning how to draw children's books . Let's talk about children's books . Do you know there is a famous book festival in the Italian city of Bologna ? After an hour and many more clicks , I found myself watching a YouTube video on how to make the meat sauce Bolognese . In other words , I had fallen down a rabbit hole and wasted an hour . But , at least , I got an idea for dinner ! Here are some notes on usage . We often describe what kind of rabbit hole we get lost in . For example , if you get completely overtaken by your research on climate change , you could say you “went down an environmental rabbit hole .” There are many verbs that you can use along with “rabbit hole .” You can get lost , fall down or get stuck in a rabbit hole . But where did this come from ? And that is another way we use this expression . It can describe a completely strange situation or an all-consuming situation . By all-consuming , I mean a situation where you lose touch with reality . You lose yourself a bit . For example , once on a trip to Coney Island , New York , I got lost and ended up in a very strange place . There was a play going on and everyone was dressed up . A band was playing strange music and the lights were all different colors . I had definitely fallen into a rabbit hole ! But this time it was Anna's Adventures in Wonderland ! And that's all the adventure we have for you today .
