I think I need a join

[Critters]

I think the following could be done with some sort of JOIN, but I am now 
sure how:



[country]:
id, country, number
1, Germany, 27
2, Japan, 30
3, United States, 18

[days]
id, day, countryA, countryB
10, monday, 1, 3
11, tuesday, 2, 3
12, wednesday, 1, 2

[result I want]
10, monday, Germany, 27, United States, 18
11, tuesday, Japan, 30, United States, 18
12, wednesday, Germany, 27, Japan, 30

Hope that makes sence :)

I can get it to join on either countryA or countryB but not both :|
