Ox Name Puns

So my sister is writing a research paper for her PhD and it involves titanium dioxides. This is an actual email my Dad sent the family email chain while we were discussing the paper (all names have been changed for privacy):

“"Aunt Jane! Can you use the term titanium dioxides in a sentence so we can better understand its meaning?" asked her curious niece at the Thanksgiving family meal.

"Sure" said Dr Doe, "Mr and Mrs Tanium ran a tannery for years. Their son Ty used to shoot water buffaloes for sport, but his parents convinced him that he should at least save the pelts. So now his parents and Ty Tanium dye ox hides!"

Beat that one!

While I was languishing in the Language Centre, doing some semantics antics and considering how all the other linguistics students despised and derided me, I was accosted by a stout man with large glasses who made me a preposition. It was that I should collect terrible puns, to do with linguistics, in order to ingratiate myself yet further with the other linguistics students (including even the phonetics fanatics).

I'm struggling to think of a pun to do with grammaticality that both makes sense and "Is grandma tickly?" correct. I'm also stuck on 'morphologician'. (I'm not actually sure that's a particularly logical word for the subject, though I guess that's more for, er, more for a logician to worry about.)

The problem I have with writing about phonological variation is that one is constantly forced to choose between being fun or logical - very Asian!I always get in trouble with electricians, they think I'm calling them a 'dialectician' whereas in fact I'm just saying "Die, electrician."

I like pscycholinguistics – the only department of linguistics where it’s acceptable to wear a cycle helmet. My Australian accent is terrible but I like to think my Sath Efrican one is predicate. My favourite accent is Received Pronunciation, because it is the accent chiefly used by invisible Japanese people who are ordered online. When the first recipient of an invisible Japanese person got the parcel, they wrote a complaint saying "Received but can't see Asian" and the name stuck.

Why did the speakers whose native languages weren't English, but whose only shared language was English, but they weren't very good at it and kept on having to stop to think about it, stop talking to one another? They came to an agreement. (Get it? If not, write your answer on a pastecard and paste it to the below address.)

What did the 'a' say to the 'the'? "You definitely are ticklish, 'the'!"

Why was the small man eaten by the large bear, which was proportionately bigger than him? It had, er, relative claws.

I think the reason there are so many speakers of Russian is because they all partake in an activity called "copulae shun". (Ok, ok, I know, that was Pushkin it.)

I know a man called Hillary who can, might, should, did, must, shall and will ride an ox. We call him "Ox Hillary".

I always think the verb 'to be' in the senten
