Beyond Expiration Date!
Alright, much to say about this one.

(Don't read this before you read the comic)

If you can read the signs on the second panel, you can find some funnies.

(Yes, it's barney the dino...since they never caught the real barney, they had to fill it with someone).

The fourth panel....thas a freezer...it was gonna have chains all over it, but I got lazy. (I know it looks like it says "no touche" but there is an "I" after the h)

Oh, why isn't gordon in his HEV suit? Because Gordon doesn't have it in the beginning of HL2, therefore Gman must have taken it off despite his "I think you've earned it".
