True story, many years ago I had to take a test to ensure my fertility was in order (long story) so I had to provide a sample.
The instructions were to place the sample in the receptacle provided but it was so small it was advised to use a larger container first. So the embarrassment of having to take a tug for this purpose was bad enough but Mrs H offered to give me a hand.
I asked her to get me something to capture my output, she went downstairs and returned with the washing up bowl, I said "how much do you think is in there?" was laughing so much it took the tension away.
