I like stupid moods too. Life is too short not to laugh :)
Life is too short to take yourself too seriously too. I can poke fun at myself all day if needs be. I find that many things in life aren't worth making a hissyfit over and that many problems can be solved rather easily if both parties are a little flexible (this is NOT in regards to this issue here). Luckily the parents of my students already know that I am extremely mistake-prone and make a LOT of them. I am grateful that they are a patient lot. I try to take the same approach.
