Is there a way to exec SP into a temp table?

Hi all

I'm doing some troubleshooting, and I'd like to insert the return set of a stored procedure into a temp table.   Since it's 75 columns, I'd rather not do a CREATE TABLE and define every column.

Is there a way to 'SELECT * INTO #tmp FROM exec sp_my_proc'?

SQL 2008R2.

Thanks in advance.
