Two Irishmen were staggering down the street, drunk as lords when all of a sudden the pub they were passing blew up into a million smithareens and a severed head rolled out onto the street. One of the drunks tottered over, bent down and grabbing the head by the hair held it up at arms length examining it closely. "Begeez Paddy, is that not O'Brien?", he finally asked. The other drunk squinted at the head and said..."Nah, O'Brien was never that tall".
