One memorable moment is when Saitama first shows his one - punch power to Genos. Genos is completely astonished. Another is when Saitama participates in the hero ranking exams. His non -chalant attitude towards the tests while still passing them easily is quite funny.
One funny moment could be when the girlfriend accidentally tickles the boyfriend's most ticklish spot so hard that he jumps up and bumps his head on a low - hanging lamp. Another is when the boyfriend tries to hide from the tickling by squeezing into a small space like under the coffee table, but gets stuck. Or perhaps when they both get so into the tickle fight that they forget they are on a couch and roll off onto the floor, still laughing and tickling each other.
Well, in the fanfiction, the moment when Cosmic Garou tries to counter Saitama's attacks with his own new - found cosmic powers is really exciting. He has evolved to a whole new level, and seeing how his powers match up against Saitama's is a big part of the thrill. Maybe he creates some sort of cosmic energy blast that Saitama has to dodge or block in an unexpected way.
There was a school play where an actor forgot his lines. Instead of panicking, he started making up the most hilarious lines on the spot. The whole audience was in stitches. It was a great example of how mistakes can turn into something really funny at school.
