Just for reference for future utilization of your joke, it's not the fastest sperm that fertilizes the egg. A bunch of the sperm reaches the egg and all work together to erode the outer layer. The egg gets fertilized when the layer is broken down enough for sperm to get in. Ergo, "fastest sperm" literally means nothing.
Actually you were probably like the, for example, 1,000th sperm to reach the egg and got there the moment those other 999 sperms tore the wall down. So basically you did about nothing and you weren't so fast.
But we all did this.
