I had an erection
I had an erection like a hot dog at a food truck, and then it went flat when I found out it was just a free sample.
I had an erection when I saw the movie trailer. Then I saw the actual movie. I was like, 'What the hell is this?'
I had an erection when my friend said he got a promotion. Then I found out he got a promotion to the same job.
I had an erection when I got the invite. Then I saw the venue. It was a park. In the rain.
