While the pair of them argue over who spent what, the fish monger is first to serve a summons which Albert refuses, "You can stick it up your kilt for all I care!"
No amount of slurs will stop the local businessmen though, who arrive en masse and crowd the yard, court orders in hand. Panicked, Harold bolts the front door and shoves a shotgun out the mailslot (as depicted on the front of Complete Steptoe boxset.) In a desperate attempt to prove his pater is barking mad and therefore not responsible for his debts, Harold puts a two cornered hat on his father, sticks his hand in his waistcoat and opens the door long enough for everyone to catch a glimpse of Albert as he sings La Marseillaise!
You'd think this image of a madman who thinks he's Napoleon would've worn out its comedy welcome long ago, but not in the capable hands of Steptoe cast and crew, as evidenced by the thunderous laughter and applause of the audience.
Now our heroes are trapped in their home, their growling stomachs greeted only by 2 particularly unappetizing tins and a packet of biscuits. Harold observes, "What good's that? One burp and you're empty!"
