The Boy Scouts were out collecting bottles for a fund raising activity. One ambitious but nervous young man knocked on a door and a sour-faced lady came to the door and asked:
"What do you want, Sonny?"
"D-d-do you have any beer bottles for the Boy Scouts, M-m-m-ma'am?" he asked.
"Look here, young man, do I look like the kind of lady who would drink beer?" replied the lady.
"S-s-sorry, Ma'am," was his reply.
"W-w-what about vinegar bottles?"
