My Moustache and Me is a song sung in the episode, "Moustache Toby" when Toby gives himself a mustache to be rough and tough to ride the mechanical bull.
Lyrics
Toby: Hey there, pardners look at me
I'm tough as a fella can be
Name is Moustache Toby yes, siree
Now I'm rough and tough
The cowboy cactus, that's me
When I ride that bull tonight
It'll be quite a sight
My mustache makes me rough and tough, you see
Life is so much better
Now that we're together
Yes, my mustache and me
Yes, my mustache and me
