Note on Return and Cancel Return URL's: It seems that PayPal does not support returning to URLs with variables in the URL which is the main construction of Joomla URLs (index.php?option=my_component&task=celebrate). Thus, if you want PayPal to return to pages other than the home page, you may need to enable SEF either using Joomla's built in SEF feature or a 3rd party component such as sh404sef.
