  M2-branes can blow up into BPS funnels that end on calibrated intersections
of M5-branes. In this quick note, we make the observation that the constraints
required for the consistency of these solutions are automatic in
Bagger-Lambert-Gustavsson (BLG) theory, thanks to the fundamental identity and
the supersymmetry of the calibration. We use this to explain how the previous
ad hoc fuzzy funnel constructions emerge in this picture, and make some
comments about the role of the 3-algebra trace form in the derivation.
