F.F. Bruce apparently took the saying to heart: The preface to volumes 5-8 of Geoffrey Bromiley's English translation of Kittel's Theologisches Wörterbuch zum Neuen Testament contains this comment:
"A great debt is again owed to Professor F. F. Bruce of Manchester University for his invaluable and indefatigable labours in proof reading. If some errors still slip through the net—and we are grateful to readers who call attention to these—there is the consolation that Dr. Bruce in particular has been able to correct not a few errors in the original German."I read somewhere that Bruce proofread TDNT while commuting to and from Manchester.
