comics - Does Hobbes ever do anything that Calvin himself could not do?

So this question got me thinking that, except for pure Calvin fantasy (i.e. Spaceman Spiff, where nothing is real), is there ever a comic where Calvin claims Hobbes did something and Calvin could not have possibly performed himself? This one comes close, but Calvin could have tied himself up

Note that we don't have to see Hobbes having done it, just that it would have very difficult or impossible for Calvin to have done it.

A pretty compelling one is this strip, where Calvin had no opportunity to take the cookies without Susie noticing:

I also find it interesting that "real" Hobbes appears in the second pane.

Then there's this one, where Calvin would probably have some serious difficulty getting that high up a tree while holding a water balloon on his own, but more convincingly, Calvin is shown leaving the water balloon at the base of the tree before he climbs:

There's also a few where it's unlikely Calvin did something. There's the tied up one in the OP, for example. There's also this one, where Hobbes probably stole a piece of cake:

There's this one, too, which, assuming it happened as shown, would be very strange if Hobbes wasn't involved:

There's some honorable mentions as well, although I didn't feel they were strong enough to explicitly mention above. They hint at things done by Hobbes to Calvin but one could imagine Calvin doing them to himself:

But Watterson left it intentionally vague, so as with all questions related to Hobbes' existence, we can never be 100% sure.
