What are the confusing behaviors of college roommates that make you laugh?

College roommates have many confusing behaviors. Here are some examples that I find funny:

1. After lights out at night, roommates will suddenly start imitating the sounds of various animals, which makes us all laugh.

On one occasion, my roommate suddenly opened the door while taking a shower, and then shouted "I am Superman". As a result, we all jumped with fear.

Roommates like to play music in the middle of the night, and always choose some strange songs, such as "Little Apple" and "The Most Dazzling National Style", and they laugh every time they hear it.

Roommates often make all kinds of strange gestures in bed, such as handstand and tumbling, which make us feel like clowns every time.

5. Once, my roommate played magic in the dormitory, and as a result, his finger got stuck in the magic props. We quickly helped him get him out, but the whole process was funny.

My roommate likes dancing in the dormitory. He always chooses some strange dances, such as belly dancing and street dancing. Every time I see him dancing, he laughs his head off.

7. roommates often make some funny expressions and actions in the dormitory, such as putting on a surprised look and then suddenly turning into a smirk expression, which makes us feel like a clown every time.

8. Once, my roommate imitated the lines in the movie in the dormitory. As a result, his pronunciation was so funny that we all doubled up with laughter.

9. My roommate likes to tell cold jokes in the dormitory. He always chooses some very unpopular jokes. Every time he tells a joke, he laughs his stomach hurts.

10. Roommates often do some strange things in the dormitory, such as slapping with pillows and making masks with towels, which always make us feel like clowns.
