Need your creative ideas - quickly!! Options

[Sweet Greetings]

Tomorrow is my oldest sons 8th birthday and my middle sons preschool graduation. I am putting out a train sign for my 8 yr old, but sadly all my graduation signs are rented out! I really want to put something out for my 5 yr olds graduation. We're super booked up this weekend with signs and so the only things I really have left that I might be able to get creative with are our fireman and cowboy... I was thinking of putting the fireman out for him with some sort of unique saying (to make it look like we purposely chose to use a fireman). What can I say??? If not the fireman, anything come to mind for the cowboy?

I guess I could just put "YeeHa! Cameron graduates from preschool today!!" on the cowboy and just leave it at that. I live on a small cul-de-sac so it's mainly just for my son, but I'd still love to hear your ideas. The fireman is one of his faves, so I'd like to use that one, but I just can't think of anything even semi-relevant. I'm kicking myself for not keeping one of the graduation signs... but I didn't want to turn down a rental (1 rental can easily turn into many).
