Once when I was assigned to read the WT lesson, the conductor took me aside during the Public Talk to say that he couldn't use me because of my 'stubble' (???). That is, unless I went home to shave & made it back in time to read the lesson. I was so angry that I simply returned to my seat without a word...while he went off in search of his replacement (i.e., good, obedient robot..)
Interestingly, the lesson that Sunday included a picture of Jesus & the disciples in all their bearded glory..
