How to remove all rows from a table except first two and last?

I've seen a lot of questions about how to select all but the first and last rows of a table, but I want to know how to select everything except the first TWO rows and the last. Right now I have this to select all but the first two:

$("#sometable").find("tr:gt(1)").remove();

and I need some way to get the last one as well. Maybe some way to combine with

:not(:last)

?

I'm fairly new to jQuery and any help would be appreciated.
