Unsuccessful product launches

Jellyfish fingers
got off to a slippery start

The chain of Dutch mountain bike stores
faced an uphill struggle

The coathanger aerials
received a poor reception

and for the Drive-Thru brothels
it was touch and go.

Signs that I would really like to smuggle into a Zoological park and stick by the enclosure of the appropriate animal..

Hardcore Prawn
Ungrateful Swine
Python Schmython
Vlad the Impala

and, at the entrance of the park, just below the opening hours
"Do not open if the seal is broken".

Literary cocktails

Tequila Mockingbird
Pride and Prejudisaronno
The Old man and the Chablis
