Crossover Fan Fiction

I recently got head over heels into the series "Chuck".
Love on first sight you could say ^^

Now I am wondering if anybody knows where to find some good crossover fanfiction including that series...

Preferable Xovers with SPN, Psych, SGA/SG1, Dead like me, NCIS, Sentinel, Boston Legal
and esp. Numb3rs (two geeks named Charles...)

Thank you sooo much!!!!  ^__________^

(PS: I am always seeking for more SPN/DLM crossovers including Dean/George =P )
