Teh is understandable. I have done it a few times myself. But what the blazes is "tegh"?
And Charles the First had the plague? I thought he lost his head.
I thought he lost his head as well.
"Tegh" happens when typo-ing 'teh' and your fingers hit the g key.
I've done that as well.
I usually catch it first.. sometimes not.
But it's my patented signature typo.
(Especially if my sis is anywhere nearby. She has that sisterly hex field that messes up my typing.)
