I would never have thought of putting guacamole on pizza but really, how wrong can you go when combining two delicious things?
I mostly put it on out of desperation to have something more than cheese and salsa on the pizza. :P I found that the taste of the guac got lost in the cheese taste though, so overall, I probably wouldn't do it again.

*Makes note of the tea & ice water tip*
I find that drinking tea makes my mouth feel dry, but does nice things to my throat. Whereas the water will dry out my throat and leave me making smacking sounds into my mic. Drinking them both smooths out the negatives, letting me keep the positives.
