Never give up.

So in the episode, he was sued by Guy Business for constantly climbing his tower, resulting in him getting banned from using any climbing-grade suction cups as well as his entire stash of suction cups (takes up most of his house) being confiscated from him.

After several failed alternatives, he felt like giving up until he was suggested the most unlikely of things to climb with. You can figure out what suction cup-based item he used. His confidence regained, he was back.

Business man was frustrated by this and calls off the case, permitting him to climb his tower on weekends and to have his stash of suction cups back.

What really sells this is his speech.

"You just don't get it, do you?

You're really going to ban me from ALL suction cups?

Plungers can be used as suction cups.

So can dent pullers for fixing dents in your car!

Mounts for your phone that stick to your windshield!

Those little rubber-based shower hooks!

Foam darts with the sticky ends. YOUR MOM!

Suction cup therapy, DO NOT LOOK THAT UP!

Have you EVER considered the human mouth as a suction cup?!

I can and WILL climb with all of these things IF I MUST!"

So yeah. If you ever feel like giving up, think of Suction Cup Man. Even when things weren't looking good for him, he managed to get back to doing what he enjoys.
