Yeah, that's a little extreme there, a few other measures that would have been a bit better:
1) Shuffling all the tools around in the thing...funny, but still dangerous.
2) Hiding the whole thing...depends on how long it stayed hidden.
3) loosening the wheels so it falls over when he moves it....I think this one would have been about right, noisy, embarrassing, good for laughs, no real harm done.
But drywalling the thing? Yeesh, that's not 'practical joke', that's "he got my cousin pregnant and didn't marry her" stuff.
