I have found that if a person enters into a public relief facility and unwittingly opens that cheap roll-out window sash due to the "heat" the previous occupant created while doing his "business" owing to the lack of sufficient ventilation otherwise and then attempts to practice calling on his newly acquired rabbit squeal per the written instructions included in the packaging in an urban environment he will immediately draw the attention of nearby canines, their owners and then in turn, the local constabulary, in dutiful response to the plaintiffs entreaties long before he can conclude his turn on the porcelain and dispose of the resultant production well before he is able to master the intricacies of the recently obtained reed instrument.
