Scrambled eggs words...

That's what the handy dandy discount MENSA calendar has in store for us today - ready to play?

Unscramble the letters below and find the missing letter you need to complete each word. The missing letter is the same for all of the words.

I G T I ?

C U C T O N ?

Well, there you have it! Bonus points if you can use all of the words in a sentence. And like always the answers will be found later in the comments. See you then!
