That reminds me - when I was younger I had trouble remembering how to spell definitely vs defiantly and would often get it wrong on my papers. So, I spent some time trying to think of a situation where it would not matter. I came up with the following: "My dad said I can't go to the party to night, but I'm [definitely/defiantly] going anyway.".

In Canada, the next sentence would be:

“NSERC had temporarily suspended our funding so if you have any questions, I’ll be pulling double shifts at Tim Horton’s.”

Sounds like a very scientific rap video.
