Funny Thing Happened on the Way to London - S3-E5
Corrected entry: When Hogan goes to shake hands with Baumann, he grabs and raises Baumann's arm to make the wrist gun fire upwards. As it fires, it takes Klink's hat off. Upon inspection, Klink's hat has only one hole, as if fired through from underneath. The gun fired at the peak of the hat, therefore, there should be a second hole about the level of the top of the eagle on the front of the hat.
Correction: The second hole is there. It is below the wing of the eagle. If you look closely, you can see a dark spot where there shouldn't be one.
