It's only about a 6 on the funny scale, but it's the best we could find ... so congrats pal, you were just good enough to beat average competition.

Michelle Obama wanted to personally thank Beyonce for singing the National Anthem at the Presidential Inauguration in D.C. today ... and then ... this happened.

Yes, that's POTUS watching the whole thing go down.

The meeting also set the stage for a TMZ PHOTO CAPTION-ORAMA!!
