In public debate he has stated that if "somebody borrowed the quote without going to check back on whether Mark Twain had said that, obviously that would be a serious charge"; however, he insisted emphatically that he himself did not do that, that he had indeed checked the original source by Twain.
Vo verejnej debate k tomu povedal, že „ak by niekto použil citát a neoveril si či to naozaj povedal Mark Twain, tak by to bolo, samozrejme, vážne obvinenie“, ale dôrazne trval na tom, že on to tak neurobil, že skutočne preveril pôvodný zdroj od Marka Twaina.
