signs, signs, everywhere there's signs

so since i'm doing a not so great job at keeping up with will's 'baby book,' i feel the need to document a few things here.
1. he's 17 mos and not yet talking (though he says "hi" "mom" "uh-oh" (often in reference to the toilet bowl that is off limits), and "up" (though it comes out like 'ba' (which is not quite the phonological process we are working on)
2. this isn't really that big of a deal or that far outside of the norm, but heck his mom's a speech therapist, so...what's he waiting for...not to mention his dad is waiting for a little bit of glory..."da da" isn't that tough is it?!
3. given that i'm a speech language therapist, we work on language...language...and more language, and he is leaning the language part quite well---he signs, gestures, points, grabs our hand and directs us to what he wants, and when all else fails, he waves his arms around here and there, hoping someone will get his point.
4. if i were to fill out a 'language inventory' as of today, here are the "signs" he does:
(does this say anything about his priorities in life?!)

- more (hands together)
- please (patting his chest---though when he first learned this one, he'd pat/ hit my chest...

my M-I-L: "he keeps hitting me, im not sure why he's doing that?"
me: "oh, i taught him that (kinda sorta) it means "please"
my M-I-L: "so he hits us in the chest to say please?!"
me: "yeah, well...we're still working on that"

- basketball (yes he did learn this sign in march during all of that glorious madness, and yes he did think the sign for basketball and tv was universal that month- heck, so did we)
- fan (this was the first sign he ever used)
- light (second sign)
- on/ off (to go along with fan and light---our electricity bill suffered a bit the month he learned these)
- dog (snapping the fingers)---he gets quite a finger work-out at the dog park, talking about all of the dogs
- all done (motioning wiping his hands)
- open (hands together and then up and out)---this may be his current favorite as it applies to opening containers, tubes of paste, doors, drawers, and yesterday he even used it to open the computer (and even used "please" right after)- interesting he used "open" for the computer vs. "on" ...
- eat (this one has been especially helpful as of late...when he gets up in the middle of the nite, and we can't figure out what's wrong...last nite he finally told me right off the bat---of course i couldn't see the sign, so he kept tapping me on the shoulder and doing his sign---finally i got smart enough to feel around, and sure enough, that growing boy was hungry.
- no (quite a favorite)
- yes (a dramatic head back and then down--followed by laughing, and then usually 'no')
- bye-bye (he uses this to people, though his timing is sometimes off and he often waves after they've left. he also uses this to indicate he's about to do something that otherwise he wouldn't be allowed to do---like "bye-bye- im going to walk into the street now" or "bye-bye i'm going to walk around the block by myself right now"
and the newest sign (and my current favorite)
- pirate's booty (a yummy healthy kid favorite snack) which is putting one hand over his eye like a pirate. (i could only be funnier if i could get him to say 'arh' at the same time...we're working on that
