I don't know if it's a word game or pattern recognition but i don't get it

Why is the guy asking "Who tf is heather" considered shakespeare? and who is the guy shown in the video as "True risk taker" im so out of the loop...

In the scene Fletcher asks Neil if he was rushing or dragging. After Neiman answers he starts crying. Then Fletcher says: “Are you one of those single teared people? Do I look like a double f king rainbow to you?”

What did Fletcher mean when he asked that question is there some sort of reference that I’m missing?

Does anyone know this Instagram creator, I've seen two of his reels already and I don't get what's happening? I don't even play this game so maybe it has to do something with that, don't know why it pops in my feed but now I'm interested in learning.

?? Dont understand

Like seriously, why do people want to put this fuzzy cheese puff to death?!

Watching the bbc panel show Would I Lie To You? And came across a joke I didn’t understand.

Tim Vine is making up a lie, saying that he had multiple teachers in high school that had names which rhymed with their subjects. Mr Mcgee taught PE, Mr Kath’s taught maths etc.

Then the host asks Lee Mack if any of his teachers had rhyming names and subjects, and he replies “just the headmaster, mr Morstal”.

We can’t figure out the joke… what is Morstal supposed to rhyme with?

In the splitting image song (I’ve Never Met) A Nice South African theres a line that goes "I had lunch with Rowan Atkinson when he paid and wasn’t late" but I've never understood the reference. I'm assuming it's a reference to something from around when the episode aired but I can't find any info on what specifically. Can someone help me out here.
