He arrived to investigate a bicycle theft reported by Frau Kowalski. His arrival did not leave the best impression; he arived on a bicycle and fell off it right in front of Frau Kowalski. He also had problems locating his note book, so he could write down the description of the thief.
His idea to catch the thief was to use his own bicycle as bait and leave super glue next to it so that the thief could get stuck. However, he ended up getting stuck in the glue along with Frau Kowalski.
