Eukaryotic mRNA Intron/Exon Boundary Consensus Sequences?

	Can anyone point me to a good reference?

All I know is that functional introns usually begin with GT 
and end with AG.  Are there known exceptions?  How rare are 
they?  In short, given a random intron, what is the probability 
distribution for the composition of its first and last two 
base pairs? 

Thanks,  Jared

EXTRA BONUS QUESTION:  Does this probability distribution 
depend on the species?
