Being a little picky, as I sometimes like to be, I'd like to point out another corruption in the Silly Wizzard version.

For at school or at college the bolus of knowledge I never could gulp till with whiskey combined.

Bolus, not basis.

A bolus is like a cud, a mouthfull of food. It fits nicely with the image of gulping.

It's a mighty song and deserving of much singing.
