To be fair, TIOBE is an awful way of determining actual usage. It's "methodology" is to search for +"<language> programming". Is Transact-SQL really used by nearly as many people (as of the latest index) as Perl or Python?

Here's some oddities (from Google currently, at least):

+"c programming" +"objective-c"

+"basic programming" +"perl"

+"c coding" vs +"python coding" vs +"perl coding"

+"java coder" vs +"ruby coder"

+"java programmer" vs +"c programmer" vs +"python programmer" vs +"perl programmer" vs +"objective-c programmer"

+"transact-sql programming" +"2014" vs +"transact-sql programming" vs +"perl programming" +"2014" vs +"perl programming" vs +"cobol programming" +"2014" vs "cobol programming"

...and the madness of +"basic programming" +"perl" +"2014" vs +"basic programming" +"perl" vs +"basic programming" +"2014"

-T.
