Well, just one to do the physical change. BUT, you will need... 5-10 to discuss which replacement bulb is best Another 5-10 to discuss the environmental impact of light bulb changes Another 5-10 to debate the origins/ histories of light bulbs, Another 5-10 to lament how light bulbs just ain't what they used to be Another 5-10 to work out how many different words they can make from the letters that comprise L-I-G-H-T B-U-L-B And... whether you want it or not... there will be at least one blaming either light bulb prices, quality, or their environmental impact (or maybe all three!!!) on those currently holding political offices. ;)
Golden Retriever: The sun is shining, the day is young, we've got our whole lives ahead of us, and you're inside worrying about a stupid burned out bulb?
Border Collie: I can do it just as quickly and efficiently as any human can. And then I'll replace any wiring that's not up to code.
Dachshund: You know I can't reach that stupid lamp!
Rottweiler: Make me.
Lab: Oh, me, me!! Puhleeez let me change the light bulb! Can I? Can I? Huh? Huh? Huh? Can I?
Newfoundland: Let the Border Collie do it and then you can feed me while he's busy.
Jack Russell Terrier: I'll just pop it in while I'm bouncing off the walls and furniture.
Poodle: I'll just blow into the Border Collie's ear and he'll do it. And by the time he finishes rewiring the house, my nails will be dry.
Cocker Spaniel: Why change it? I can still pee on the carpet in the dark.
Doberman Pinscher: Change it?? While it's dark, I'm going to sleep on the couch.
Irish Setter: Huh?
Boxer: Who cares? I can still play with my squeaky toys in the dark...
Mastiff: We Mastiffs are NOT afraid of the dark.
Chihuahua: "Yo quiero Taco Bulb."
Pointer: I see it, the light bulb, there it is, there it is, right there....
Greyhound: If it isn't moving, who cares?
Australian Cattle Dog: First, I'll put all the light bulbs in a little circle....
Old English Sheep Dog: Light bulb? I'm sorry, but I Don't see a light bulb. Maybe if you just trim the hair over my eyes a bit...
Samoyed: Oh, sure, I can do that. I've seen the folks do it. I'll just move this chair so I can stand on it, and then I turn the bulb ... turn ... Dam! I sure wish I had opposable thumbs!
Just needs one person to take the bulb to an electrical repair shop to have the filament replaced instead of tossing out the whole bulb. Only costs 20 bucks and they make it look like brand new.
