To Do Calculate

To Do Calculate
When Simon thought he had finished his final PhD thesis, he went to get it checked by his supervisor, little did he know the error he had made.

His supervisor pointed out the critical, grammatical error he had made, writing 'to do calculate'.

Simon embraced this mistake, letting watchers of his vlog know about the mistake (this would be the second mistake Simon made). It later became the subject of more memes. Simon also had the quote printed onto a t-shirt which he wore in his 'From primary school to PhD' video.

Simon in a tweet said there may be a limited run of "To do Calculate" t-shirts available in the future.
