Jesus H. Christ

I am not the only guilty party who's said it.  But have you ever wondered what in the H does the H stand for??  I did some research (God BLESS Wikipedia HA!) and this is what I discovered from multiple (unverified) sources:

-  There have been various theories, but the one that seems most plausible is that it comes from the Greek monogram for Jesus, IHS or IHC. This is formed from the first two letters plus the last letter of His name in Greek (the letters iota, eta, and sigma; in the second instance, the C is a Byzantine Greek form of sigma). The H is actually the capital letter form of eta, but churchgoers who were unfamiliar with Greek took it to be a Latin H.

The oath does indeed seem to be American, first recorded in print at the end of the nineteenth century, although around 1910 Mark Twain wrote in his Autobiographythat the expression had been in use about 1850 and was considered old even then. Its long survival must have a lot to do with its cadence, and the way that an especially strong emphasis can be placed on the H.

Nineteenth-century Americans weren’t the first to take the Greek letters to be Latin ones — since medieval times the monogram has often been expanded into Latin phrases, such as Iesus Hominum Salvator, Jesus Saviour of Men, In Hoc Signo (vinces), in this sign (thou shalt conquer), and In Hac Salus, in this (cross) is salvation.

Wikipedia states all this and adds that it may (and I use may loosely) stand for Hallowed or Harold (which was a mispronunciation of Hallowed).

It's HILARIOUS people think Jesus had a middle name!!!
