Here's my attempt, sorry this is long but here I go:
1)Hydrolyze the ester with acid and methanol
2)Protect the exposed alcohol with sodium hydride followed by benzyl bromide
3)Hydrolyze the methyl ester again, this time with water.
4)Turn the resulting carboxylic acid into an acyl chloride using SOCl2
5)Use a methyl gilman reagent on this (CH3)2-CuLi
6)Remove the benzyl protecting groups simply using hydrogenation (H2 + Pd/C)
7)Use a grignard reagent to squeeze on the alkene (CH2-CH-MgBr).

Note the last step will produce a mixture of two diastereomers.

I don't think this comic is particularly smug though.
