  We perform a frequentist analysis of the bispectrum of WMAP first year data.
We find clear signal domination up to l=200, with overall consistency with
Gaussianity except for the following features. There is a flat patch (i.e. a
low chi-squared region) in the same-l components of the bispectrum spanning the
range l=32-62; this may be interpreted as ruling out Gaussianity at the 99.6%
confidence level. There is also an asymmetry between the North and South
inter-l bispectrum components at the 99% confidence level. The preferred
asymmetry axis correlates well with the (l,b)=(57,10) direction quoted in the
literature for asymmetries in the power spectrum and three-point correlation
function. However our analysis of the quadrupole (its bispectrum and principal
axes) fail to make contact with previously claimed anomalies.
