The scene:  a Velux factory somewhere in Denmark.  The actors:  Haagen and Paavo.

Haagen the apprentice:  this glue is amazing, it's the strongest stuff I've ever seen.

Paavo: it holds the windows together, keeps the different layers of laminate together - it has to be really strong.

Haagen:  well I've a little left over, what should I do with it?

Paavo:  put it on the glass and we'll stick the instructions on.

Haagen:  but won't the glue make it really difficult to get the instructions off?

Paavo:  indeed.

Haagen:  especially if the workmen leave them on?

Paavo:  especially.

Haagen:  and if the window is high up in the roof?

Paavo: even better.
