I'm not afraid of shots either (although when I get blood drawn, I have to put in so much effort just to stay still; I guess I'm somewhat scared because I shake/shiver...)
Point is, I didn't expect the flu shot to hurt as much as it did. Still beats the flu though.
Flu. Flue. Fly. Flea. Alliteration.
I love this limerick completely unrelated to the flu:
A fly and a flea in a flue
Were trapped, so what could they do?
"Let us fly," said the flea
"Let us flee,"said the fly
So they flew through a flaw in the flue.
