This is an epic rant on the scale of Christian Bale 'Terminator Salvation' proportions and contains some really colourful language.
All we know at the moment is that this is spreading like wildfire on the t'internet but the cynics are saying that it is actually a prank set up by Jimmy Kimmel.
**UPDATE*** (Kimmel has come out and denied their involvement so is this is the real thing? Terryfying)
***Update Again**
Here is THE TRUTH behind the rant. Actually it was a Prank but not Kimmel..it was Funny Or Die ...and we know know that Dennis Quaid IS sound and IS a great Actor! PHEW! :-)
