Is NCAA and NFL Football to strict with touchdown celebration?

I could understand college football being more strict than the NFL, but hey, aren't these games a big show. It seems like now players cant even celebrate; We all love to see endzone celebrations, just some can be a bit silly and just plain stupid i.e. (a few years back Joe Horn with the flip cell phone- in the endzone) but for the most part they are all very good. But whats your opinions are the regulations two strict?? And whats your favorite celebration?
