Well, you could teach "pick up that thing for me", weave between legs as you walk,
rollover, "leave it", go get your leash, "go wake up (insert name here)", seek forwards and seek back, which is a command I use to get my dogs to check out the area for any dangers before i go in. I taught my kelpie to round up the cat and the other dogs when i want them inside, though I wouldn't suggest cat herding for most people!
You can also teach "say your prayers" and "go shake hands with them", where you point to the person you want the dog to shake with.
