From random web browsing comes this funny explanation:
Last week, Mordechai Coheni, assembling a falafel, noticed skillet burns on the pita resembling the face of Jesus Christ. Shortly thereafter, 8,000 curious pilgrims trek to the falafel stand in Jerusalem to view the sacred icon.
“Why is this a surprise?”, asked Dolores del Rios, a pilgrim from Spain. “Jesus was a Jew- he probably grew up eating pita. He is probably more comfortable appearing on a pita than a tortilla.”
I can’t exactly call this “rational” thought, but it is showing “some” thought… and it did strike me as very funny.
