If you don't mind Python:

#!/usr/bin/python
# emulates uniq -c
# *-* encoding: utf-8 -*-

import sys

res = {}
count = 1
for x in open(sys.argv[1], "r").readlines():
try:
res[x] += 1
except:
res[x] = 1

for key, value in res.items():
print "#%i %s occured %i times!"%(count, key.replace("\n", ""), value)
count += 1
res = {}

Or just use uniq and the -c switch!
