My Mother is a Daughter in law Puns

So we were sitting at at the table having hotdogs for dinner. My mother-in-law and I then both went to ask my daughter for something at the same time, me for the sauce and the MIL for my daughters glasses so she can clean them. Then we ended up taking turns asking

My MIL then commented that it was good that we didn't ask at the same time otherwise she would be cleaning the bottle and I would be trying to put glasses on the hot dog.

My wife then turned to me and said "Then it would be a Seeing Eye Dog!" And promptly burst out laughing.

This was made all the more special, since my wife is only now just coming out of a 5 year melancholic depression. Yay!

EDIT: Changed wording to make it clearer. Thank you very much from both myself and my wife for all your positive thoughts. :)

The wife and I had her mother over whilst eating dinner, a la Taco Bell.

After trying some of our daughter's food, my wife insists that it is way spicier than she expected, and proceeds to tell my mother in law she has to try it - Saying "I think it's spicy nacho sauce."

After a moment or so, I piped up "I wouldn't know, it isn't my sauce." and put on my best I made a pun face.

MIL loses it, and my wife looks confused for a few seconds and goes to offer me a taste before the groaning ensued. Victory!
