Reference different places to the same footnote

How can I have a single footnote but place the mark for it in multiple places on the page (in fact, in a single table). Assume that \footnote{} is used liberally in the rest of the document.

Use \footnotemark[num] the second time you want to place a mark in the text.

Objection, your honor:

Have you ever seen that in a book? Probably not. Because: Two footnotemarks numbered with e.g. an "8" raise the question whether it is a typo. But your readers can not come and ask you, if you really meant to do it this way.

Please, if you'd like to refer to the same text, make a footnote saying (maybe in better English than mine):

¹ Long sentence at: Wallace, Infinite Jest, p. 1234.

² See footnote 1.

What you'd like to do is against an old and sensible tradition.

In technical documentation multiple footnote marks are quite common. –  Andrey Vihrov Feb 15 '12 at 10:00
    
And how do you distinguish between error and purpose? Especially technical documentations suffering under many flaws, knocked together in minimal time -- especially there it is a no go. –  Keks Dose Feb 15 '12 at 10:16
