Funniest Parts?

[Mystery]

Cave Johnson was the funniest character. Think about how comparably boring the old Aperture labs would be without his quips and rants over the top. In a part of the game that was basically just sliding and jumping around which was great by itself, his voice just adds to the whole thing.

Brilliantly funny game, though. To pick a few favourite lines would be hard as every line was obviously meticulously thought over, but here's a good couple.

'Aristotle versus MASHY SPIKE PLATE'
Every line of the useless turrets before they get chucked into the incinerator. One of the only points in the game i had to pause and just listen to every one (like Cave's lemons rant)
Space.

Didn't even notice this the first time, but during the final battle this line is hilarious:
"Reactor explosion timer destroyed. Reactor Explosion Uncertainty Emergency Preemption Protocol activated. This facility will self-destruct in two minutes."
