Dumb and Dumber 

Jim Carrey is a one-of-a-kind talent, known for an amazing ability to make nearly anything funny. In the classic ’90s comedy, Dumb and Dumber, there are plenty of standout lines that fans love. One of which some may find more cringeworthy, was completely made up by Carrey.

Carrey’s Lloyd and his co-star Jeff Daniels’ Harry are constantly hitting each other and acting juvenile, as their recent hitchhiker sits between them and is very annoyed.  After he tells them to stop, Carrey pauses and improvises “Want to hear the most annoying sound in the world?” He then makes a sound that only Jim Carrey could do. If you look closely, you can see Jeff Daniels’ start to laugh before the camera pans away.
