It seems as if Irish-American talk show host Bill O'Reilly was the only person who took up Irish-American actor Charlie Sheen's offer to debate 9/11.

Hollywood star Charlie Sheen challenged several media pundits to debate him on his 20 bullet points about 9/11 but O'Reilly was the only one to take him up on it.

Now, CNN anchor Larry King - who was all set to host the debate - says he's shocked that no one else would step up to the plate.

Sheen had challenged Meghan McCain, Rush Limbaugh, Sean Hannity and Bill O’Reilly to do a debate with him on what he termed "unanswered questions surrounding 9/11."

Now, that would have been some show.

McCain is Scots Irish through her father, Senator John McCain; Hannity and O'Reilly are both New York Irish and Sheen is Irish through his dad Martin Sheen.

Given all they have in common, they could well have turned on the only non-Irish in the bunch, Rush Limbaugh.

Maybe Limbaugh was just afraid of the Irish!
