To me it suggests a new way to tap a keg on a
Barvarian or Swiss streamlet

.......they are both earing shorts [short trousers that is] ....
It is not a jug being filled, but a 2 litre stein.....others are shown as part filled .......the tappers hat, together with the oarsman's braces give it away
Having said that.... how about ..
''Klaus......ya head is nein good you have too much gas turned on".....
