Naughtie later apologised for his "Spoonerism" – in reference to Dr William Spooner who notoriously switched letters between words inappropriately.
In the last line, you can see Woods following Schmidt's lead by switching out letters for their phonic cousins of S or D (iD = it), or, more simply, capitalizing S or D in the "wrong" places (waS = was).
The tornado-prone stocks are chosen on the basis of being widely favored by those mutual funds that are favored by mutual fund switch letters.

Switching one "letter" of genetic code-replacing a "C" with a "T -meant T -meanterence betheen differenceand betweenair.
To return to our example above, the set \(\{\textrm{A}, \textrm{B}, \textrm{C}, \textrm{D}, \textrm{E}\}\) is invariant under all permutations of the letters \ \textrm{A}\) through \ \textrm{E}\): no matter how we switch these letters around, we end up with the same set.
For example, the permutation that switches the letters \ \textrm{A}\) and \ \textrm{Z}\), mapping all the other letters to themselves, transforms \(\{\textrm{A}, \textrm{B}, \textrm{C}, \textrm{D}, \textrm{E}\}\) to \(\{\textrm{Z}, \textrm{B}, \textrm{C}, \textrm{D}, \textrm{E}\}\).
But when the speaker asked them to switch from letters to numbers (A, 1, B,2 ) most gave up on the task in the middle of it.
