I can't remember if I remember the 60's.

I can remember not remembering the 60's.

I remembered not to rememeber the 60'...or the early 70's either!

I remembered the 60's for awhile...but then I forgot I remembered it.

I remember all of the 60's!...but I forgot where I put it.

Man, all this remembering is a real drag!

...what a drag, kind of a drag.

(my memory of the 60's is actually very vivid...my 60's didn't start happening until about '69-'70 or so...)
