Our reading
An editorial interpretation.
The speaker promises a very quick tidy-up, claiming someone can be clean and presentable within five minutes. Realising that 'back on the street' could sound seedy, they hurriedly add that they mean nothing of the kind. The joke lies in the self-conscious correction, which draws attention to the innuendo.
