Talk:Vaseline

I had read about the same trick in Heinlein's Time Enough for Love when the time traveling Lazarus Long is told of it by his grandfather when Long enlists to fight in WW I. Was this a common idea or is it a HT lit allusion? I would be more comfortable if there was a line where Walsh reflected he had learned the trick from a Yank corporal named Bronson (Long's assumed name). ML4E 21:05, May 11, 2012 (UTC)
