I completely missed yesterday's quiz - I wonder how that happened. My answer - toilet flush handles your toothbrush (yayagal - I think you might want to re-read the OP - it looks like you answered the wrong question. I don't think baby's giggles have germs - sorry if I overstepped here)

A 12 pack of beer "and" clamato juice....just had to say it. lol Category: Alcohol/Judy & Lars ahead of me....

I also think it's McDonalds. It was a huge thing for Aspen Colorado to get one. Then, it was the busiest place in town!

I agree with Lucille, this question needs definitions. I also agree with mosquitos being the deadliest, due to the diseases they can carry and therefore spread. And humans being the second deadliest. But maybe that should be reversed, humans first and mosquitoes second. I don't think dogs would rate very high in the 'deadly' category, unless the question is world wide, then perhaps they could be because of rabies. Rusty
