name calling?

i have a kid named Phu this week. you can imagine my enjoyment with this.
so i've experimented with comments like:

"sup, phu" or
"get in line, phu"
"freeze phu!" (during tag)
"phu, gimmie your money" (for t-shirts)
"where you be at phu" <---- callan's favorite
"i pity that phu" (when he fell into the creek)

and my all-time fave, "you a CRAZY phu!"

ahhh. it's the simple things that i look forward to in my job.
