It's easy, just get a soccer ball, stuff it full of enriched urineanium, get some of that c-fore stuff and super-glue it to the panels, attach disco-strobe igniturs, damper the back of each c-fore encrusted panel, stick it in your New Balances (size 98) and light a match (while sitting next to a person that looks like Hulk Hogan).
All spelling is intentionally correct here, I'm hoping Saddam will intercept this.
If a nuke is popped in the U.S., it will not be a backyard project. It will have come from Iraq or Iran. The same, for that matter, with any serious bioweapons attack.
