I love irony. Here are a couple of ironic statements I have heard from preachers:
"We do not allow solos in this church, because it leads to pride." Then the preacher preaches an entire sermon solo.
"You don't need a commentary. Just read the Bible." When a preacher says that, prepare yourself for a 30 minute oral commentary on a single verse, complete with the historical background and context, definitions of Greek or Hebrew words, maps, charts, and lessons on the nuances of the grammar of an obscure language.
If you have heard or said an ironic statement from the pulpit, please share it. I would love to read it.
