Grep from specific column in one file based on another file [Please help!]

Hey Guys, to keep it simple, I have an idFile:

Code:
1006006
1006008
1006011
1007002
......

and famFile:

Code:
1006 1006001 1006016 1006017 1
1006 1006006 1006016 1006017 1
1006 1006007 0 0 2
1006 1006008 1006007 1006006 2
1006 1006010 1006016 1006017 2
1006 1006011 1006016 1006017 1
1006 1006016 0 0 2
1006 1006017 0 0 1
1007 1007001 1007950 1007015 2
1007 1007002 1007014 1007015 2
......

and I need to grep all the lines from famFile in which its second column contains all the numbers in idFile. The returned results should be like this:

Code:
1006 1006006 1006016 1006017 1
1006 1006008 1006007 1006006 2
1006 1006011 1006016 1006017 1
1007 1007002 1007014 1007015 2
......

grep can't do that. How about this:

Code:
awk 'BEGIN { while(getline <"idFile") id[$0]=1; }
        id[$2] ' famFile
