If you have children, they sometimes go in the yard and dig a hole to China.  If the hole is dug, gophers sometimes come out of the hole.  When you see the gopher, place your sim (I think it has to be a child; can't remember) on the gopher to chase it away and praise them for chasing away the gopher.  Then the message will come up about the go-pher it trophy.  I hope this helps.  Good luck!!

I usually drag them to the sink to take a drink then praise them before they actually drink the water.  Something will come up with the trophy for curing hiccups.
