For all intensive purposes, on occasion, I can be pedantic.

What?

Yeah, makes no sense right?  It's because it's not "for all intensive purposes", but rather, "for all intents and purposes", like "in every practical sense".  When you say "for all intensive purposes", you are saying,  "for all purposes that are characterized as intense".  You're also indirectly saying, "I don't read much."

Also, it's not "nucular", but rather "nuclear".

It's not "expresso", but rather "espresso".

Not "expecially" or "excape", but "especially" and "escape".  You also don't "axe" questions.  You "ask" them.

When you're at the ATM, you don't enter your "PIN Number", you enter your "PIN", because the "N" stands for "number".

Yup, for all intents and purposes, I can be a pedandic asshole sometimes.
