Strategy/ Odds re: Little PP on Button against nutjob LHE : Help !!!

[El_Hombre_Grande]

I can't figure out what do do with this situation. On the button with a tiny pocket pair, (say no higher than 44) with maniac or maniacs in the blinds, capable of re-raising with nothing and continuing onward after the flop. Assume that BB nut calling range is huge. But The trouble is, in my mind at least, is that every board is scary and my nutjob friend raises pretty much randomly. I feel like I'm lost at sea, just pretending to understand the situation. It is a LEAK. Help.
