Benedict Cumberbatch

 (This is the first go at a new form I dreamt up, inspired by the way diagrams of recessive and dominant genes, which influence physical characteristics are drawn - Alleles)

A. His eyes are pale blue, yet not recessive;
B His hair, once pale gold-brown is dark with 'Just For Men;'
C His jutting cheekbones hint at Scots descent;
a One sees him everywhere, which seems excessive;
D His face is rather long but not too thin;
b His quiff is waved and English, so that Ben
c Gets all the rather 'upper' roles. And his ascent,
E To stardom seems foretold within his genes
F Since he is from the upper echelons, that is, he's posh.
d His white teeth flash a big American grin
G But this can't detract from his acted, English reserve.
f He seems quite clever, but that is just tosh,
e He's thick as two short planks, although this means
g His acting skills are great.  We should preserve
F(Since he is from the upper echelons , that is, he's posh)
a Those institutions whence he came. His CV is impressive.
C His jutting cheekbones hint at Scots descent;
b I'd like to hear his 'Cabin Pressure' once again.
B His Hair, once pale-gold brown is dark with 'Just for Men'
D His face is rather long but not too thin;
A His eyes are pale blue, yet not recessive.
e His politics are middling: bluey-reddish-greens
c The road he traveled (straight not bent)
E To stardom seems foretold within his genes.
f He's not one of the lads, he does not josh.
d As Holmes he sometimes plays the violin
G But this can't detract from his acted, English reserve
g. Perhaps we havethe idol we deserve.
