I'll start.
When I went to the GP, after getting my urine tested, because my husband and I are trying for a baby, I got all the symptoms including late periods but the pregnancy test is negative: "I'm just looking at your urine test, and it seems that...it's positive! (2 seconds later) for an UTI."
My ex, explaining that I should have given him another chance after cheating on me twice "I could have done it. It took me three times to pass my driving test!"
A website on which I have an account, that asked me to enter my password in order to retrieve my password that I had forgotten.
Grrrr
