What a dilemma lol! I have some too at the moment and have been making a super fast kind of guacamole for snacking... avocado, bit of bottled pasta sauce and some tabasco.
However you already do guacamole so I found some other interesting ideas for you
http://au.blogs.yahoo.com/better-homes- ... o-recipes/ I think I would like that pumpkin and avo salad there at the bottom

http://www.abc.net.au/queensland/stories/s1256642.htm Potato and avo salad
http://whatscookingamerica.net/Fruit/AvocadoPie.htm << dessert! Might try that one
Apparently you can also marinate and bbq them, batter and deep fry them and use them in smoothies.
So have fun!
