Water Ox 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!
