Scenario: (About American cartoon-The Simpsons)
(A little boy around 10-year old was fishing by the lake.)
Litle Boy: When it comes to catching trout, nothing beats the German light infantry.
Bart: Beautiful, aren't they?
Little Boy: Yep. I'm gonna huck them at cars.
Could someone decode the implication of the sentence which I highlighted in blue for me? What is the link between German light infantry and trout? Thanks!
