Have him help with chores. Seriously - you'll actually be more interested, get some of your housework done (slowly), and he'll totally dig it.
At 16 months my son LOVES sweeping, vacuuming, and using a damp rag to wash just about everything. It helps if i am doing the same chore, but for those things he doesn't even need me. He can help put things away - all i have to do is do a sample so he knows where it goes. He can take silverware or napkins and put them on the table. He can pour from one thing to another - so pouring the dog food in the bowl or the measured flour into the bowl both work. He has a stool and he absolutely loves standing at the sink with me while i do dishes. In the yard he will pull up plants, rake, or move rocks around while i do yard work.
By 3, my daughter can help with a lot of the cooking (no raw meat, high heat, or sharp knives, but everything else), setting and clearing the table, more advanced and less supervised sweeping, washing, etc. She loves to move clothes into and out of the washer and dryer, add the soap, press the buttons to make them go. She is learning to fold clothes or napkins and put them away.
I really like this approach because i don't feel as insane, and my kids are both learning how to do chores and learning that their contribution to the household helps. The appreciate the time with me, and i appreciate that they learn to respect me as a person, not just a playmate.
In other news, now that the weather is getting nicer, i'm appreciating that our sandbox, and a bike apiece can keep my kids busy on their own outside for hours.
