[Noisebridge-discuss] rats laugh when tickled

[Jake]

who knew?  I guess now we need to make an audio transverter, so we can 
hear the noisebridge mice laughing at us.  apparently these rats laugh in 
the 50khz range, so probably noisemice laugh at a higher frequency than 
that because they're so tiny.
