<human>: Can you summarize the given text in a few sentences?

No, I didn't shit myself, but it wasn't loads better.

Got on the bus on the way home from lectures at uni with friends from my course. The bus is full so I'm standing which is fine, though it's in one of the more open sections of the standing area so I need to reach up for the rings to hold on to. Which is also fine.

At this point I should also mention that it's the last day of lectures and a big programming project hand in day, so I am knackered. I am also a big guy, and of my skills good balance isn't one of them.

Deciding that I might fall over if I remain hanging onto the rings, I decide to reach for a pole a couple of feet away. As I do so the bus goes round a corner and I lose my balance. It takes me a while to properly lose it though, so there were a good five-ten seconds where I knew I was going to fall on someone, but wasn't yet in a position to apologise profusely.

Inevitably I fall, and the student, middle-aged woman and old man seem reasonably OK with the situation. I feel like a tit. I stand up to see a friend of a friend absolutely pissing herself with laughter, trying to do it subtly. My friends pretended not to notice at the time, but between the lot of them I'm not going to hear the end of it. Or get that bus again.

At least I didn't shit myself.
<bot>: Big guy falls on people on a bus, people see, mock him, no one shits themselves. Sounds far less dramatic or entertaining than the full version.
