Intercultural Puns

Background: I'm living in Germany and have a German roommate who can speak some English. He did Realschule (completed 10th grade), but mostly ditched classes. I try to teach him when I can and vice versa.

We were watching Walking Dead. The episode was right after the prison gets stormed. Rick and Carl lock themselves in a house, and Carl ties a knot that he's super proud of... Blablabla... A few minutes later, knot is quickly falling apart as zombies try to break in.

I absentmindedly said: "Cool knot, bro" Roommate: "(K)not cool, bro"

I just looked at him with a mixture of surprise, pride, and wondering still if he knows what a dad joke is.

I posted a picture on Facebook of my grandmother wearing a fantastic hat from when she was my age. My family is Swedish, the word for grandmother (mother's mother) is Mor Mor. He commented on one picture thusly:

Dad: I will be posting a collection/selection of your Mor Mor (not your Mor Mor Mor) but actually some may contain both your Mor Mor and Mor Mor Mor who is you mother's Mor Mor. But you knew that.

(Then correcting his omission)

Dad: I meant to indicate it would be a hat based collection but got mor than confused.

Bonus points for attempting to learn Facebook, dad.

I am currently in a intercultural communication class in college. Because its the beginning of the semester we always have to do some goofy activity and because the class is about culture everyone would tell something interesting about theirs. So this little Asian kid in class starts talking about customs growing up. He says how when he was little he remembers his father farting, and his dad asking why he is not clapping "in this culture you clap after your father farts." The whole time hes telling this I am thinking...no way...this dad is a savage. I kind of got a feeling he was starting to pick up on it, he started talking slow and thinking about it. Long story short: he clapped after his dad farted presumably for years, practicing their culture. What do you think?
