A couple in their 40s had his mum and dad staying over. Dad accidentally found some viagra in the bathroom cabinet. He asked his son about it. "Does it really work?" "Sure does." "Could I try one?" "Maybe, but they're, like, 20 bucks a tablet" "No worries, I'll leave a $20 note under your pillow before we go." "Well, OK, you know where they are..." After they leave, he looks under his pillow to find $70. He sends Dad a text. "Dad, I said $20, not $70..." "The $50 was from Mum"
