Did you saw that? Did you saw that?!!

I hear this a lot - and by prevalence you'd be shocked
I guess its been a problem for me too

But what is wrong in this sentence? Logically, spoken language shouldn't have so many rules

Did is the past tense of DO
Saw is the past tense of SEE

Marry them together and you get divorced quicker than the bone thugs can rap or perhaps britney's actual Marriage - at least her 1st

I'd usually back up my argument by bursting into song - U say thats funny?
I say its practical

Take for example MAE's song 'We're so Far Away' (Citation based on my bias - MAE Rocks!)
From Toledo, to Tokyo,
the words were scribed on every page,
and now there’s books up on our shelves.
Did you know how you would move us, did you know?
When the lights first came upon us,
and we saw The Everglow.

If it doesn't sound right musically or verbally - Consider Revising
And every time you hear yourself say this think somewhere out there
someone's either singing or playing Britney's 'Oops I did it again'

And yeah did you bought that is also incorrect!
