the standard they're, their, there plus your and you're really do bug.

I'm not positive if this is a grammatical error or not because someone smart once tried to correct me on this, but this bugs:

"He only has $100."

I'm 90% positive it should be "He has only $100."

I never say anything but it eats my brain every time I see this.

Also, people who mix their idioms. Today I heard Terry Bradshaw say "...with every once of fiber in me..."

This kind of thing makes me think of Khan putting one of those crawly bugs in my ear every time.
