Carpet
A guy (we'll call him Aaron) was laying down carpet in some woman's
home. As he was finishing, he got a craving for a cigarette. Aaron
looked around and discovered that his cigarettes were missing. He
did, however, notice a bump in the carpet, and figured that he had
laid carpet over the pack without noticing it there. Aaron decided
rather than to take up the carpet, he would get a hammer and pound
it into the ground so no one would know.
When he finished that, the owner of the house walked into the
room and commented on what a nice job he had done.
''Aaron, The carpet lookes wonderful!'' she exclaimed. ''Here
are your cigarettes; I found them in the kitchen. Oh yes, and by
the way, have you seen my gerbil?''
