There is more to these little stories than you might realize at first glance. Emphasis added to this one.
WASHINGTON—President Bush collapsed in the Oval Office after spontaneously expelling a 3-pound kidney stone from his bladder, sources reported Tuesday. According to witnesses, the president was attending his daily Iraq War briefing when he suddenly began shrieking loudly and clutching his abdomen, a mixture of blood and urine pooling rapidly around his feet. Bush was able to maintain consciousness through more than 20 minutes of excruciating pain, even after the jagged, grapefruit-sized crystal aggregation shredded his urethra and dropped from his left pant leg, finally rolling to a stop on the presidential seal in the middle of the Oval Office carpet. Bush is resting comfortably at Bethesda Naval Hospital.
A comparison is being made between the death and injuries of American soldiers in Iraq (blood) and Bush's outsized civilian kidney stone (urine, which is associated with cowardice; the huge size of the stone represents Bush's legendary incompetence). The stone, which shreds his urethra (indicating wishful castration, I think), rolls down his left leg (left=Democratic presidential victory) and comes to rest on the presidential seal, symbolizing the disgrace that Bush's cowardly false bravado has brought to both the office and the country. The presidential seal itself is in the middle of the Oval Office carpet, a piece of decoration of which Bush is very proud (he always points it out to visitors) and which itself is very yellow (cf. "urine").
Is this at all all funny? I don't know, but as I said, there's more there than you'd might think at first. Can I have my honorary degree now?
