Parlour tricks will get us all arrested for prostitution while the pimp sneaks out the cleverly hidden trapdoor placed, somewhat ironically, beneath the 'Prohibition Era' pilsner keg.

Don't blink, for godsakes, don't blink!
Edit: Perhaps Jelly Bean should make you sing 'Strange Fruit' as a login. That way you will surely remember where you came from.
