Occupational humor, some puns among trade. Like the one from job before retirement: Woman in shower hears door bell ring, ask on intercom who's there? answer was 'blind man' , woman thinks just a begger, give a dollar to him--and no need to put on bath robe or towel to open door. Man looks at her and say the Graber Roman Shades are prepaid delivery, mounting instruction in the box, color code indicates deep pink like your skin tone. Variations of joke use the product code numbers at times. Rayovac workers used to tell of domestic argument ended when wife drop box of AAA on husbands head, got charged "assualt WITH batteries'. Worked with a lady that had second job with ABS, joked about 'line of Bull' coding. For the humor impaired, business impaired : Graber is brand name for Window covering maker- a top 4 in market that has many 'window blinds' on market , Rayovac makes lot of batteries for lot of appliances , and ABS is a artificial insemination product provider for cows /dairy herds.
