When Emil attempts to hide in the park and falls to the ground, the white waistband of his Calvin Klein underwear can be clearly seen. However, in the final scene, which takes place shortly afterwards, he wears plain black boxer briefs.
Although Emil tells the others to meet at the Krugkoppelbrücke (and the episode being titled after it), the bridge they jump from is actually the Streekbrücke, which is about 500 meters further up north.
