Go, Dog! Go!
Go Day could be a great day for games. There's the ancient game called Go that you and one opponent could play.
I'm sure this wasn't intended originally, since the game didn't exist at the time, but I guess you could count Pokemon Go as part of your celebration today.
You could alternatively use the lower case verb form of the word and just go somewhere - to the store, to the neighbors', across town, across the country, around the world.
How did "went" ever become the past form of "go" anyway?
It should be "go", "goed", "goed". That way we wouldn't have to correct 3-year-olds.
Dum, dum, deee, dah-dah, dah, dup...
Go, Pack, Go!
It's almost football season. Gotta go. Catch you tomorrow.
